Heteralepas gigas (Annandale).

The type-specimen was taken by Capt. Worsley in Bali Straits 

 on a cable at a depth of 160 fathoms. There are numerous speci- 

 mens from the Java Sea (lat. 10° 22' 30" (?S.), long. 120° 7' 30" 

 E. : 130-500 fathoms) in the Baffles Museum. The latter are con- 

 siderably more swollen and distorted than the former and show that 

 the animal must have had a gelatinous appearance in life much 

 like that of the Alepas found attached to medusae on the surface. 

 The hairs I described on the external surface of the type do not 

 belong to the animal but are the remains of a Hydroid attached to 

 it. I reproduce a photograph of a specimen from the Java Sea. 



The type-specimens of Poecilasma (Glyptelasma) gigas were 

 found attached to the peduncle of examples of this species.

Subgenus Glyptelasma, Pilsbry. 



This subgenus only differs from that which contains the typical 

 forms of Poecilasma in the peculiar structure of the base of the 

 carina. Pilsbry regards it as intermediate between Poecilasma and 

 Megalasma and as probably ancestral to the latter^ under which he 

 places it. The species now to be described, however, though it 

 evidently comes into the subgenus is in most respects a true Poe-
