An Account of the Indian Triaxonia collected by the Roi/cd Indian 

 Marine Surve)f Shijy ^Investigator.' By Fraxz Eilhard Schttlze, 

 Ph.D., M.D., Professor of Zoology at the University of Berlin. 

 The German origiual translated into English by RoBERr von 

 Lexdesfeld, Ph.D., Professor of Zoology at the University of 

 Prag. Calcutta : Printed by Order of the Trustees of the Indian 

 Museum, 1902. Price 16 Rupees. 4to. Pp. 113; pis. xxiii. 



The work before us includes the substance of three separate papers 

 published by Dr. Schulze in the ' Abhaudlungen der Kouigl. 

 Preussischen Akademie der W^issenschaften ' for 1894, 1S95, and 

 1900, on thellexaetinellida collected by the ' Investigator' in 1885- 

 1898. These papers have been thoroughly revised by the author, 

 and then translated into English. 



Previous to the 'Challenger' expedition only four species of this 

 beautiful group of sponges were known from the Indian Ocean. 

 Upwards of fifty are now enumerated by Dr. Schulze, of which 

 only twenty-one were known previous to the ' Investigator ' expe- 

 dition. 



The group, however, is widely distributed in different parts of 

 the world, and some of its representatives, such as the " Venus's 

 flower-basket" from the Philippines {^Eaplectella aspergillatn), and 

 the glass-rope sponge from Japan (^Ifyalonema Sieboldi), may be seen 

 in every museum. They are mostly deep-sea forms with skeletons 

 frequently resembling spun glass or lacework, and are often of 

 very elegant forms. 



Dr. Schulze's work is too highly technical to appeal to any but 

 specialists, except, perhaps, as regards the beautifully executed 

 plates. He commences with an introduction, giving a list of the 

 twenty-one species known before the 'Investigator' expedition: 

 then follows the descriptive part of the work, in which two or three 

 closelv printed pages are usually devoted to each species ; and the 

 work concludes with three tables of the species known from the 

 Indian Ocean, with full localities. The work is a valuable addition 

 to the literature of one of the more modern branches of scientific 

 exploration— deep-sea dredging.

By this time nobody requires to be told the nature and aims of this 

 most valuable book. As a work of reference it is indispensable. 

 "We take it for granted that there are few zoologists who do not 

 possess it ; our advice to those who do not is " get it." 



A wise discrimination in the selection of individuals has most 

 undoubtedly been exercised throughout the whole course of this 

 work. We have searched the pages of the present volume diligeEtly 

 for the names of biologists, and have come to the conclusion that 

 only a very few who deserve mention in these pages have been 

 missed—their names may be reckoned on the fingers of one hand.
