DESCRIPTION OF A NEW GENUS AND SPECIES BELONGING TO THE FAMILY PHYLLIDIIDAE (NUDIBRANCHIA: DORIDOIDEA)

A new genus of phyllidiid nudibranch, Reticulidia, is described.Distinguishing features are the reticulate pattern of smoothridges on the dorsum and the radially arranged, glandular discswhich make up the pharyngeal bulb. Additional features of theforegut are described and compared with other genera. The importanceof the alimentary system for the separation of genera withinthe Phyllidiidae is supported and its validity reinforced bythis new genus. One species, Reticulidia halgerda, is describedas new and differentiated from a second, sympatric species.Reticulidia is presently known from the eastern Indian Ocean,South China Sea and western Pacific Ocean. ^*Present address: Australian Biological and Environmental Survey,Australian National Parks and Wildlife Service.

海南小遁蛛属1新种（蜘蛛目：巨蟹蛛科）

记述采自海南省乐东县尖峰岭国家自然保护区的巨蟹蛛科小遁蛛属１新种,海南小遁蛛Ｍｉｃｒｏｍｍａｔａ ｈａｉｎａｎｅｎｓｉｓ ｓｐ．ｎｏｖ．。     

中国卷叶蛛科一新属新种记述：蛛形纲：蜘蛛目

本文记述采自安徽休宁县齐云山卷叶蛛科(Dictynidae)一新种。因该科内无可容纳此新种的属,故建立齐云蛛属Qiyunia gen.nov.并将新种定名为列氏齐云蛛,新属新种。文内列表比较了洞叶蛛亚科(Cicurininae)布朗蛛 Brommella和旋栓蛛 Lathys两近似属与新属的鉴别特征。     

寄螨科4新种和糙革螨属在中国首次发现（蜱螨亚纲：中气门亚目）

报道寄螨科4新种:北方糙革螨Trachygamasus borealis sp.nov,叉形新革螨Neogamasus furcatus sp.nov,峨眉常革螨Vulgarogamasus emeishanensis sp.nov.和四川寄螨Parasitus sichuanensis sp,nov.;其中糙革螨属为中国首次纪录。     

羽爪瘿螨科一新属三新种记述（蜱螨亚纲;真螨目）

记述了羽爪瘿螨科一新属,即新兰瘿螨属Ｎｅｏｌａｍｂｅｌｌａ ｇｅｎ。ｎｏｖ。三新种是女贞新兰瘿螨Ｎｅｏｌａｍｂｅｌｌａ ｌｉｇｕｓｔｒｉ ｓｐ．ｎｏｖ。,麻栎 蜡皮瘿螨Ａｐｏｄｉｐｔａｃｕｓ ａｃｕｔｉｓｓｉｍａｅ ｓｐ．ｎｏｖ。和榆畸刺瘿螨Ａｂａｃｏｐｔｅｓ ｕｌｍｉ ｓｐ．ｎｏｖ。对其形态进行了描述并与近缘种作了比较,模式标本保存在南京农业大学。     

槭属的一个系统

对槭属的研究历史作了简要的回顾。详细地论述了槭属植物的芽、花序、性别分花,花,果实、胚、叶等的形态特征及其演化关系。在上述论述的基础上提出槭属的一个系统。这个系统包括４亚属２３组３３系２００种。

THE ANATOMY OF BARBACENIOPSIS,A NEW GENUS RECENTLY DESCRIBED IN THE VELLOZIACEAE

Although the two species in Barbaceniopsis—B. boliviensis and B. vargasiana—have in common many features which support their inclusion in one genus, there are also obvious differences in the depth of leaf furrows, absence of hairs in B. vargasiana, and type of girder sclerenchyma in the leaf. The presence of vessels in the leaf has been demonstrated. The frequent observation that the roots cling tightly only to stems of Vellozia species is shown to be characteristic of the family. A comparison of the three genera clearly indicates that there are obvious anatomical characters which help to distinguish Barbaceniopsis and Barbacenia from Vellozia. Although it is not suggested that Barbaceniopsis be reduced to synonymy, there can be no doubt that it is very closely associated with Barbacenia.     

RADIOMYCES,A NEW GENUS IN THE MUCORALES

Embree , Robert W. (U. California, Berkeley.) Radiomyces, a new genus in the Mucorales. Amer. Jour. Bot. 46(1): 25-30. Illus. 1959.—Radiomyces spectabilis is described as a new genus and species in the order Mucorales of the Phycomycetes. This fungus readily grows in pure culture, and developmental stages of the asexual and sexual reproductive structures are described. The genus is referred to the family Thamnidiaceae, and in doing so, the family concept is necessarily broadened to include almost colorless, smooth-walled zygospores with appendiculate suspensors.     

中国地衣新记录属─小腊肠衣属(英文)

在进行《中国地衣志》的编写中,作者从采自我国新疆阿尔泰山哈纳斯湖附近的地衣标本中发现了北极小腊肠衣［Ｂｒｏｄｏａｏｒｏａｒｃｔｉｃａ（Ｋｒｏｇ）Ｇｏｗａｒｄ］（茶渍目,子囊菌门）。小腊肠衣属（ＢｒｏｄｏａＧｏｗａｒｄ）是中国新记录属,因而,也是中国地衣区系中已知的第２３４个属。本文对于该属、种在形态学、结构学、化学及地理分布等方面进行了描述与讨论。对于它和邻近属的区别也做了简要的对比。     

A NEW NEMATODE-DESTROYING HYPHOMYCETE OF THE GENUS HARPOSPORIUM

Drechsler , Charles . (USDA, Plant Industry Sta., Beltsville, Md.) A new nematode-destroying hyphomycete of the genus Harposporium. Amer. Jour. Bot. 50(8): 839–842. Illus. 1963.—A mucedinaceous parasite that destroyed a largish nematode in a maize-meal-agar plate culture to which had been added some leaf mold from an oak wood in central Maryland is newly described as Harposporium dicorymbum. It permeates the host animal with colorless septate assimilative hyphae, 2.5-8.5 μ wide, that soon put forth procumbent septate conidiophores bearing mostly subglobose phialides with 1-3 sterigmata. Its very distinctive conidia are composed of a minutely pedicellate globose part, 4-7 μ in diameter, together with a cylindrical outgrowth, 3-9 μ long and 2-3 μ wide, which is furnished distally with a short posterior and a longer anterior beak.     

Hesperotherium(黄昏兽 )——后期爪兽一新属

记述了山西天镇早更新世爪兽一新属———Hesperotherium。新属为低冠中等大小的爪兽 ,主要鉴别特征是 :吻部极度缩短 ,门齿、犬齿和第一前臼齿消失 ,前臼齿高度退缩 ,上臼齿宽大于长 ,原尖孤立 ,下臼齿后齿带发育。这是爪兽科最后的代表。中国过去在晚上新世至早更新世地层中发现的Nestoritherium ,很可能都应该归入这个新属。这个属的化石目前仅发现于中国。
