Eglisia, Callostracum, Mesalia, cC*c. 369 



founded on a unique worn shell, now in the British Museum. 

 It has been considered by Tryon identical with the variety 

 varia. Owing to the bad condition o£ the shell it is im- 

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

 he is right, in which case the West-Indian locality becomes 

 very doubtful. 



Turritclla opalina, Ad. & Rve.*, said to be from the 

 China 8ea, agrees exactly with the upper portion of a typical 

 hrevialis. Tiie fine spiral striation is precisely the same and 

 tlie style of markings (exaggi'rated in the much enlarged 

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

 that some mistake has occurred in regard to tiie locality f. 



Jeffreys states that TurritaUa siitiiralis of Forbes \, from 

 the ^gean Sea, is the same as brevialis, Reeve, partira 

 (=.var. varin), but the description given by Forbes is so 

 inadequate tliat it becomes impossible to recognize the shell 

 he had before him, which is described as only ^^ i"ch in 

 length !

Hah. Deep water. " A I'ouest du Sahara" {Locard). 



This may be a deep-water form of M. h-evialis, with flatter 

 whorls than the typical form, and somewhat narrower also. 

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

 if any, difference. Very few of the specimens of brevialis 

 (typical) I have seen show any colour-marking, but, when 

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

 undulating, irregular flammulations, as described by Locard. 



Mesalia pulchella, Pallary.

Ilah. Tangier. 



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

 varicosa, differing from the type respectively in colour and 

 sculpture. 



The animal radula and operculum are unknown, and from 

 shell-characters this species might equally well be placed iu 

 lurriiellopsis.
