1861.] M. O. A. L. MORCh's REVIEW OF THE VERMETID^. 363 



This shell scarcely differs from the type, except in the absence of 

 the punctures ; but as both states are frequently found on the same 

 specimen, this cannot warrant specific separation. I have a sHght 

 doubt respecting this species, arising from the locality being only 

 known from the shell on which it is represented, which perhaps is as 

 likely to be a Melo as Stronibus galea. It seems to me curious that 

 a shell named after Peron should be from a place that he never 

 visited.

This variety is closely allied to V. conicus, Dill., var. y, from which 

 it only differs in its deeper colour and more irregular sculpture.

 rugisqiie transversis cequidistantibus decussati, hide interstitiis 

 regulariter scrobiculatis ; anfr, mediani lati, Iceviusculi, sculp- 

 tura evanescenfe, albo et violaceo variegati ; anfractus idtimus 

 castaneus, lirulis confertis obsoletis, rugis incrementi sigmoideis,

Vermetus tulipa, Rousseau, Chenu, 111. pi. 1 . f. 2 (an 1 & 3 ?) ; 

 Adams, Genera, p. 358. 



Hab. Gulf of California, on a piece of a black Pinna (Mus. 

 Cuming). 



The figure 2 of Chenu is a pretty good representation of the 

 colour of the last part of the last whorl ; fig. 3 looks very different, 

 but approaches in appearance that of the middle whorls of the 

 described specimen.

 anfr. latiusculi plerumque contigui, liris et tceniis sape evane- 

 scentibus, rug te incrementi versus tnarginem prominentes crassce;
