 It has been consijcied by Tryon identical with the variety 

 vdiia. ()vvin<^ to the hal condition of the shell it is in>- 

 possible to speak with certaintv, but I am inclined to think 

 he is rii^hf, m which case the West -Indian locality becoinea 

 verv doiiblt'id. 



TurritcUa opnlinn, Ad. Si Uve.*, s:ii(l to be from the 

 C)hina Sea, agrees exactly with the upper portion of a typical 

 hrevial'is. The fine spiral striation i^ precisely the sann* and 

 the style of niarkinifs (i-XH(r«5 rated in the much enlarged 

 figure) is quite simihir. I am therefore inclined to believe 

 that some mistake has occurred in regard to the locality f* 



Jeffreys states that TnrritAht sutundis of Forbes J, from 

 the iEgean Si'a, is the same as hrevi'iUx, Ueeve, partim 

 ( = var. vari'i), but the description given by Forbes is so 

 inadequate that it becomes impossiide to recognize the shell 

 he had before him, which is described as only j'*.^ inch in 

 length I

This may be a deep-water form of .1/. hievlalis,\\\{\\ tJatter 

 whirls than the typical form, and somewhat narrower also. 

 As regards sculpture and coloration, there seems to be little, 

 it any, difference. Very few of the specimens of breviulm 

 (typical) 1 have seen show any coloui -marking, but, when 

 they so occur, tliey fake the form of longitudinal, reddish, 

 undulating, irregular flammulations, as described by Locard.

Ilab. Tangier. 



M. Pallary describes two varieties, var. fusca and var. 

 vurirosa, diflfering from the type respectively in colour an I 

 sculpture. 



The animal radula and opeiculum are unktiown, and from 

 shell-characters this species might equally well be placed in 

 2'urritei/opsiM.
