Gemis Cypnca. 229 



blotch is occasionally absent. A large variety occurs in 

 New Caledonia {cf. Sowb., f. 176), and a beautifully coloured 

 form (^id., f 358), is figured as being in the Lombe Taylor 

 Collection. 



C. errones. (L.). Sowb., Thes. Conch., pi. xx.. 156, 157, 

 158. This species mainly varies as to the presence or 

 absence of the brown dorsal blotch, and the plain or saffron 

 colour of the teeth ; the specimens vary much, also in size, 

 the smaller being the most brightly coloured. 



{a) cJirysopJi(za (var. nov.). Surface entirely coloured 

 golden brown, enamel of base and sides shining, pale yellow, 

 teeth and form as in type. A most beautiful colour variety 

 in my collection from Port Blair. Andaman Islands. 



{U) C. Coxi (Brazier) and {c) C. SopJiicE (Brazier) are 

 varieties ; the latter only differs in more lateral development 

 of white enamel, and yellow teeth, and of this I possess a 

 fine example ; the former a pale brown uniform variety, 

 from N. W. Australia ; dentition and base as in the type. 

 In the Cholmondeley Collection, Owens College, Manchester. 



C. cribraria (L.). Cf. Reeve, C. I., pi. xvi., f 81. Sowb., 

 Thes. Conch., pi. xx., f 161 — 164. 



{a) translucida (var. nov.). Of this well-known and 

 handsome species I have pellucid varieties from the Sand- 

 wich Islands, which have been named Peasci, but this is a 

 misnomer. It will be better to rechristen them translnciday 

 as Peasei (Sowb.)^ is preoccupied by a different species. 

 Form and dentition as in type. 



{U) Exnioiithensis (var. nov.). Another fine form I noticed 

 recently in the Natural History Museum, S. Kensington. 

 In this the dorsal markings are very rich blackish brown, 

 the white spots more sparse ; long, in size about i inch. 

 Habitat., Exmouth Gulf, W. Australia, collected by T. H. 



* C. Peasei (Sowb.) figured in Thes. Conch. XX., 166, 167; and a curious 

 monstrous var. of the same, from Mauritius, is figured Proc. Zool. Soc. XLVL, 

 f. 13, 14, 1878.
