RESEARCH COLLECTIONS 59 



Comparative Zoology collection might be estimated at over 1000, 

 but the task of searching these out and listing them is still very far 

 from being finished. 



TUNICATES 



The collection of tunicates is entirely unidentified, and even un- 

 sorted. It consists of alcoholic material in jars and bottles, in many 

 cases mixed with bryosoa, sponges and other invertebrates. It is im- 

 possible to say how many species are represented, of the approxi- 

 mately 1500 known, but a reasonable estimate would be about 200. 

 As the collection has never been studied or catalogued, there is no 

 type material. A large part of the collection came from the "Hass- 

 ler" Expedition.
