were collected in depths ranging from 90 to 1439 fathoms, and, in the 

 paper referred to, were arranged in catalogue form, but no systematic 

 details were given except in the case of Fishes and Crustaceans. In the 

 order Madreporia Dr. Alcock named and described three new corals ; 

 two, Caryophyllia ephyala and Sleplianotrochus nitens, taken by the 

 collectors on the " Investigator," and one, Rhizotrochus Worsleyi, -pre- 

 sented to the Indian Museum by Captain Worsley. The type specimen 

 of Stephanotrochus nitens is a very fine one. A complete list of 35 deep- 

 sea fishes collected during that season is given, and includes 24 new 

 species. Of the other classes noted in this part of the paper, it must be 

 mentioned that the deep-sea Holothurians were worked out, named, and 

 described by Dr. J. H. Tull Walsh, who published the results of his 

 investigations in the Journal of our Society, Part II, No. 2. Dr. Walsh 

 has described all the deep-sea forms obtained from 1887 to 1891, 

 and notes two new genera and seven new species. In connexion with 

 the study of Holothurians, I would draw attention to a valuable trans- 

 lation of a paper by Dr. Hubert Ludwig on the development of these 

 creatures, which appeared in the Annals and Magazine of Natural History 

 for December 1891. In the February issue of the above-mentioned 

 Journal another portion of the paper by Mr. Wood-Mason and Dr. 

 Alcock appeared, and this is chiefly noteworthy on account of the new 

 species of Crustaceans described by Mr. Wood-Mason, and for the very 

 good original drawing of Nephropsis Atlantica 6 Norm, which it contains. 

 The March number contained a further instalment of notes on Crusta- 

 ceans by Mr. Wood-Mason, the most interesting and important of these 

 being the full and clear description of a new crab, Parilia Alcocki. 



To the Annals and Magazine of Natural History for July, August, 

 October, November and December, Mr. Wood-Mason and Dr. Alcock 

 contributed a series of papers showing the results of the " Investigator " 

 deep-sea dredgings during the season 1890-91 ; and in the issues for 

 July and August Dr. Alcock described fully many new bathybial fishes. 

 In the October and November numbers Mr. Wood-Mason contributes 

 further to the literature of the Crustacea, and finally in the December 

 number Dr. Alcock describes certain new star-fishes. These two authors 

 have also conjointly contributed a most important paper to the Proceed- 

 iui/s if Ihr li'ni/ul Snrii-hj, " On the Uterine Villiform Papillae of Ptero-
