J30 COLLINGE : SOME NOTES ON THE GENUS PRISMA, SIMROTH. 



Through the kindness of Mr. Edgar A. Smith, I have been able 

 to examine the examples of this genus in the collection of the British 

 Museuin, and also to figure them. There are three specimems all 

 labelled V. priamatica, Tap. -Can., the localities of these are as 

 follows : 

 i. Huon Gulf, New Guinea (Dr. Comrie). Length (in alcohol) 39 



millim. 

 ii. An island in the Torres Straits, or New Guinea. Length (in alcohol) 



36 "5 millim. 

 iii. New Guinea. Length (in alcohol) 56*5 millim. 



I am entirely in accord with Simroth, wh ) regards the Huon Gulf 

 specimen (i) as a distinct species, viz. the P hrijnemanni of Simroth. 

 The second specimen (ii) is undoubtedly Prlxuia prismatka, Tap.-Can., 

 '^' while the third (iii) is quite distinct from either i or ii, and I am 

 here describing it as a new species under the name of Prisma smitlii, 

 after Mr. Edgar A. Smith, as a mark of appreciation, for the facilities 

 he has so kindly extended to me when examining these and other 

 specimens in the British Museum collection, and for his permission 

 to figure the three examples. 



Heynemann '•" was undoubtedly wrong in fancying that the draw- 

 ings of P. fourannenm, Soul., and those of P. prismafica, Tap.-Can., 

 were of one and the same species.
