Terebra bipartita, Desh, 



The above is a small slender species, quite distinct from 

 hastata, Gmel., with which Mr. Reeve has connected it. 



Terebra Peasei, Desh. 



Is a synonym of T. puncticidata, Desh., as classed by Mr. 

 Reeve, and not a variety of T. Stvainsonn, Desh., as noted by me 

 in my previous paper, p. 125. I was led into the error by the 

 typical specimens forwarded me from Europe, being wrongly 

 labelled. The species for which it was mistaken I have described 

 as T. Swainsonii, var injiexa. 



TORINIA TROCHOIDES, Desh. 



In my last paper I suggested that dealhata, Hds., might be a 

 synonym of the above. 1 discover that Mr. Hanley had already 

 decided it to be so. I am of opinion that T. conica, Pse., 

 Proc. Zool. Soc. London, 1865, is at least a variety, although 

 the late Mr. Cuming supposed it to be distinct. 



It differs from the description of trochoides in being concen- 

 trically striate and in having more color. The specimens from 

 which the description of Hinds and Deshayes were drawn up 

 may not have been as perfect as those I received. 



Margarita angulata, A. Ad. 



The above should be erased from the synonymy of Trochus 

 tantiUus, Gld., page 131 of my previous paper. 



Having noticed it in the catalogue of Australian species by 

 Mr. Angas, classed as Minolia, I was led to examine its de- 

 scription, and discover it differs from the Hawaiian species in 

 being "openly umbilicate " and whorls angular above. The 

 locality given by Mr. Adams, " Sandwich Islands," was prob- 

 ably the cause why Dr. Gould and others adopted the synonymy 

 I followed. 



Tritonidea undosus, Rumph. 



Buccinum cinctum, Quoy, should be transferred from the 

 synonymy of T. fumosus, Dill., to that of the above, in my pre- 

 vious paper, p. 104. 



Tritonidea fumosus, Dill. 



1832. Buceium undosum, Quoy, non Rumph., Voy. d'Astrol., 



Vol. 2, p. 411, pi. 30, fig. 1—4. 

 The above should be added on page 104 of my previous paper. 

 LatiruS columbarium, Chera. 

 1788. Murex columbarium, Chem., Conch. Cab. vol. 10, p. 284, 



pi. 169, f. 1637—38.
