VIII. REPORT ON A COLI.ECTION OF 



BRYOZOA FROM THE BAY OF BENGAL 



AND OTHER EASTERN SEAS. 



By Alice Robertson, Ph.D. 



The collection of brj'ozoa here reported upon was sent me bj' 

 Dr. Annandale, Superintendent of the Museum at Calcutta, India. 

 It consists of ]:)ryozoa obtained, for the most part, at various 

 points on the coast of India and from various depths in the Baj' 

 of Bengal and vicinity. Both shore and deep water species 

 are included, the bathymetric range varying from a few to several 

 hundred fathoms. 



The specific identification is accompanied with one or two 

 sj-nonyms only, referring both to a description and a plate, the 

 endeavour being simply to make the identification intended unmis- 

 takable. In case the plate referred to is not easily accessible, or 

 in those instances in which new species are described, drawings are 

 given together with a description. No attempt has been made to 

 give a complete synonymy, the authority adopted being that of 

 Miss Jelly (1889). .'Vny departure from this has been chiefly 

 on the authority of Waters, especially as given in his recent papers 

 on the Red Sea (1909) and the Zanzibar (1913) faunas. 



This collection contains representatives of forty-five genera 

 and ninety-five species. Of these nine species and one variety are 

 thought to be new to science. Two genera, Kinetoskias and 

 Farciminaria, are of special interest, since not onl}- are they from 

 abyssal depths, but also while possessing undoubted characteristics 

 of these two genera, the two species by which they are represented 

 possess other characters which link them to other but probably 

 related genera in a manner not hitherto shown. Considerable 

 interest attaches to certain membraniporas found in brackish 

 waters. Three such are considered new to science. Their mem- 

 braniporidan character was early recognized but certain other 

 characters were extremely puzzling, and it was not until the work 

 of Stoliczka (1869) on M. bengalensts was discovered that their 

 true nature was revealed. Judging from the work done by 

 Dr. Annandale on brackish water forms together with these river 

 species of Membranipora, India abounds in brackish water vari- 

 ational forms of much interest. 



Considerable difficulty has been encountered in this investiga- 

 tion since the writer has been unable in most cases to secure 

 actual specimens for comparison. My thanks are specially due 

 to Professor Trevor Kincaid in so cordially lending the facilities of
