Two loose nectophores (length 19 mm. and breadth 14 mm.; the smaller one i8Vj mm. 

 and 13 mm.) belong probably to the same specimen. The sketches remind us of Gegenbaur's 

 Praya maxima, and as the whole interior of these nectophores is badly preserved, there is no 

 question of describing it. We have simply before us the gelatinous substance of two nectophores 

 which appear to be allied to Praya maxima Ggbr.

Stat. 276. Lat. 6°47'.s S., Long. i28°4o'.5 E. Cat. 156. formald. 4°/^. 3 loose nectophores. 



One of the three nectophores is absolutely torn and shapeless, the two others are not 

 much better and do not differ from the description given by Huxley. Huxley himself was verj- 

 careful in giving any definite specific name to his only loose nectophore. We are in the same 

 position and confer the name of Lilyopsis diphyes only with the greatest reserve. 



The length of the two nectophores is 8^'o and 7 mm., the breadth 5 and 5^'. mm.; in 

 this respect they are smaller than any other Prayid described up to this date. 



In both nectophores there are remnants of somatocyst, stem and appendages and it is 

 to be noted that in the smaller one the hydroecial aperture is situated in the middle of the 

 ventral part only and that it does not extend to the anterior part of the nectophore.
