136 Mr. E. A. Smith on some Shells 



being ignorant of Mr. Brazier's paper in the Proc. Linn. Soc. 

 N. S. Wales. 



Mr. Brazier has kindly called my attention to his descrip- 

 tion, and sent a splendid series of specimens (including the 

 actual types) of his Pupina Angasi, which at once proves its 

 identity with P. louisiadensis. 



Another species of Pupinella from the Louisiade Archi- 

 pelago has also received the name Angasi. This species was 

 described by H. Adams in the Proc. Zool. Soc. for 1875. 

 His description was read in April and published in August. 

 Mr. Brazier's species appears to take a few months' priority, 

 and must therefore be retained ; the description was read 

 in January of the same year, and published (so I am informed 

 by Mr. Brazier) the following May. Under these circum- 

 stances 1 have much pleasure in adopting for the shell 

 described by Adams the name " Pupinella Smithii, Brazier," 

 as kindly suggested by Mr. Brazier in a letter dated 

 April 15th of this year. 



2. Pupinella Brazieros (Smith). 



Megalomastoma Brazierte, Smith, Ann. Mag. Nat. Hist. 1888, vol. xix. 

 p. 424, pi. xv. fig. 15. 



Hab. Ferguson Island and Cape Pierson, Normanby 

 Island, D'Entrecasteaux group, south-east of British New 

 Guinea. 



Since describing this species, I have had an opportunity of 

 examining a series of specimens of the genus Pupinella from 

 the Louisiade Islands, which shows that the characteristic 

 notches in the labrum vary considerably in depth and other 

 respects in species otherwise very much alike. 



Quite a transition from a largely developed loop-like slit 

 on the columellar side to a mere indication of a notch is 

 observable in P. grandis, Macgregori, minor, Smithii, Mou- 

 linsiana, Angasi (Brazier), and Eosseliana. The study of 

 these forms now points to the conclusion that the present 

 species should also be located in the genus Pupinella, and 

 not in Megalomastoma. The labral notch may be said to have 

 entirely disappeared in this species, which, however, still 

 possesses certain characters in common with several of the 

 other species, namely, the uniform reddish colour, the well- 

 thickened reflexed peristome, which is united to the body- 

 whorl above in the same manner, the circum-umbilical ridge or 

 keel, and the sudden descent and contraction of the body- 

 whorl near the aperture.
