his former work proposed to distinguish two of these by the 

 names of duplex and decussate/. Both of these now become 

 synonj'rns, for the Australis of Reeve is the same species as 

 Australia, Lea, the latter having priority, and Lea's second spe- 

 cies of that name was changed by its author to 31anillaensis, 

 before the publication of Dr. Brot's name duplex. 



31. Bernardii, n. sp. Hab. . Closely allied to corpo- 



rcsa, Gould, but may be distinct. 



M. luteola, Dunker, 31. bicolor, Brot, and 31. Taliitensis, Dun- 

 ker, = 31. corporosa, Gld. 



M. Moricandi, n. sp. Hab. ? 



" compressa, " " 



" Ghristobalensis, n. sp. Ins. Salomon. 



" asperula, n. sp. Hab. ? appears to resemble 31. 



scopidus, Reeve, from Tahiti. 



31. Damonis, n. sp. Archipel. Salomon. 



M. Australis, Lea, Victoria Riv., is re-established, and decus- 

 sata, Brot, proposed instead of it, is made a synonym. Australis 

 of Reeve is the same species. Dr. Brot believes Balonnensis and 

 tetrica of Conrad to be only local varieties of one species; but 

 they are quite distinct. 



31. furfur osa, Gould, is believed to be a non-spinous variety 

 of spinulosa, Lam. ; and 31. Therpsiehore, Gould, as well as 

 Feejeensis, Reeve, to be varieties of 31. tetrica, Gould. 



M. calcitrapa, sp. nov. Hab. — ? 



31. Zolingeri, " Java. 



M. subaurita, " Hab. — ? 



31. f rater na, Lea, is the adult form of Pirena (31.) subim- 

 bricata, Phil. 



Melanopsis princeps, Lea, is a young Pirena. 



Pirena aspera, sp. nov. Hab. — ? 



Hemisinus Osculati, Villa. In the synonymy of this species 

 is placed 11. Binneyi, Try on.* When we described the latter 

 species we pointed out the difference between it and Osculati. 



We still consider them distinct, and the opportunity for com- 

 parison is now afforded by Dr. Brot, who figures an authentic 

 specimen of Osculati.

In these days of careless and hasty authors, when the would- 

 be student is encompassed by towering heaps of synonymy, 

 crushing his aspirations and involving labor that none but those
