Expedition I have degraded the two following Melanise, M. Tatei, 

 Brazier, and M. subsmilis, E. A. Smith !, to varietal rank. 



Cyclostrema cingulifera, A. Adams !, This Philippine shell 

 is very much larger than C. Tatei, Angas, but otherwise they 

 seem identical, in which case C. laivis, Phil., will fall in as another 

 synonym. 



Cyclostrema micans, A. Adams !, and Liotia Angasi, Crosse !, 

 are the same by comparison of types. Adams located his species 

 in the right genus, and his name takes priority. 



Phasianella variegata, Lamark !, and P. Angasi, Crosse !, 

 are conspecific ; Crosse's type is a somewhat overgrown indi- 

 vidual, but otherwise not different from the Lamarckian type. 



Clanculus Yatesi, Crosse!, October, 1863 = C. Menkei, Ads. 

 and Angas, in British Museum. 



Monodonta lineata, Lamk. ! = Trochus badius, Wood. 



This admission is on the back of the tablet carrying Lamarck's 

 types, to which is added M. rosea, Lamk. ! M. Peroni, Lamarck, 

 only differs by having white flames. 



These and other congeneric species usually referred to Elenchus 

 should be quoted under Phasianotrochus, Fischer. 



Caniharidns decoratus, Adams and Angas !, P.Z.S., 1864, and 

 Trochus Tiberianus, Crosse !, Jour, de Conch., Oct., 1863, are the 

 same as already suspected, and referred as synonymic under 

 Gibbnla smaltata, Fischer, 1879. Crosse's name is the older, and 

 the shell should be quoted as Gibbula Tiberiana. G. aurea, 

 Ten. -Woods (1876) is another synonym. 



Gena nigra, Q. and G., was not seen in the Paris Museum, but 

 a shell identically that which is locally referred to that species is 

 present, though unnamed. 



Fissurella nigrita, Sowerby !; is rightly identified ; the types 

 are larger than F. Pritchardi, Hedley, which I regard as 

 synonymic. 



Parmophorus convexus, Q. and G.!=P. australis, Lk.!=ScUTUS 

 anatinus, Donovan. 



Acmaea flammea, Q. and G.! ( Patelloidea). This species has 

 hitherto been known to local conchologists as A. conoidea, Q. and 

 G., Angas in 1865 being the first in error. The types are worn 

 smooth externally, and show a cruciform coloration in brown ; 

 each flame is frequently broken-up into three or more streaks. 



Acmaea conoidea, Q. and G.!, which is much smaller than 

 A. flammea, has a circular aperture and fine radial threads. 

 A. calamus, Crosse and Fischer, authentic specimens of which I 

 have not seen, is probably the same. 



Acmaea septiformis, Q. and G.!, is rightly identified. 



Bullinella arachis, Q. and G.!, is rightly identified. 



Haminea cymbalum, Q. and G. The type of this species I have
