DEPARTMENT OF ZOOLOGY. 135 



Among the specimens received, attention may be called 

 to the rare Peripatus tholloui, biollegi, and corradui, 

 described by Prof. Bouvier. 



The additions to this small but very interesting group 

 keep the collection well in advance of that of any other 

 Museum. 



Echinoderma. — The additions include the last batch of 

 the " Discovery " specimens, of which altogether nearly two 

 hundred specimens have been acquired. 



The great interest of the Antarctic Echinoderma lies in 

 the valuable evidence they afford as to the extreme variability 

 of this group ; good series of Cycethra verrucosa, of Ophio- 

 steira antarctica, and others have been obtained. 



Of the Echinoderma obtained by exchange from the 

 Mus. Comp. ZooL, Cambridge, Mass., U.S.A., mention should 

 be made of Aporocidaris milleri, Synapta vivipara 

 from Jamaica, Rosaster alexandri, and Ophiostigma 

 isacanthum. 



Echinodiscus auritus from Lhanban, E. Africa, was 

 presented by Mr. W. T. Sneyd. 



Among the species selected from the Stanley Gardiner 

 collection mention may be made of the rare Brisingaster 

 rohillardi, Echinolampas oviformis, the little known 

 Ophioteresis elegans, and the rare Neoplax opkiodes ; there 

 is also an interesting example of an immature Gorgono- 

 cephalus verrucosus, and a good supply of the early stages 

 of several Ophiuroids. 



Vermes. — The most important is the collection made by 

 Prof. Benham, f.r.s., in New Zealand, and determined by 

 Prof. Ehlers, of Gbttingen, who has published a full report 

 on it. 



Mention ma}^ also be made of a rare round worm 

 {Strongylus ostertagi) from a collection presented by 

 Mr. Godman, F.R.S., and of nine earthworms collected at 

 a height of from 6,000 to 9,000 feet on the slopes of 

 Ruwenzori. 



Anthozoa. — With the exception of the fourteen specimens 

 collected by the " Discovery," there was no special object of 

 interest in the small addition made to the collection of these 

 animals. 



Polyzoa, Hydrozoa, Porifera. — A collection of Indian 

 fresh-water Sponges, Hydrozoa, and Polyzoa (including 

 co-types), received in exchange, per Dr. N. Annandale, 

 from the Indian Museum, Calcutta. 



A set of fragments removed from the type specimens 

 of Hexactinellida from the Indian Ocean, described by 

 Prof. F. E. Schulze.
