364 M. O. A. L. MORCh's review of the VERMETIDJi. [NoV. 12, 



group of Mr. Bridges mentioned by Carpenter, Cat. p. 306, in the 



note. 



This variety is very Uke the last ; but the colour is much obliterated, 

 and the last whorl is partly free and erect. It is chiefly notable for 

 the resemblance of the first whorls to Vennetus contortus and V. 

 macrophragma, some specimens of which are found on the same shell.

Hab. L'Oceandes Indes, aTimor (Mm5. nos^r.). Elle varie beau- 

 coup, et neanmoins je la crois distincte de la S. arenaria. Lam. 



Of the figures quoted by Lamarck, none agree with the descrip- 

 tion. Gualt. tab. X. f. L, is F. arenarius, L. ; and le Mossier of Adau- 

 son, regarded by Deshayes (Lam. ix. p. 65) as the type, is not from 

 Timor. Siphomum nebulosum, Dillw., cannot be called lotiga, undato- 



curva. 



The upper figure 3 of Chenu's plate seems tome to correspond ex- 

 actly with Lamarck's description ; the figure 3 (left) is very likely le 

 Massier of Adanson, and does not agree with the description, although 

 it is possible Lamarck regarded it as a variety, as it really approaches 

 to V. arenarius, to which Lamarck likens it. 



26. Vermetus (Aletes ?) granifer, Say. 



Covered with longitudinal, contiguous, slightly elevated, granulated 

 strife. Shell subcylindric, contorted ; inferior side flat ; the whole 

 surface is composed of very numerous, small, contiguous striae, each 

 consisting of a single row of granules ; these series are alternately 

 smaller. The continuity of the tube within is interrupted by obhque 

 dia})hragms : it sometimes approaches the spiral form ; and one spe- 

 cimen has three complete volutions of much regularity. 



Diam. of the largest specimen f inch.

Hab. Tertiary-beds of Maryland {Say). 



According to the figure, this species must be closely allied to V. 

 centiquadrus, var. peronii. 



27. Vermetus (Aletes?) tortrix, Goldfuss. 



T. Icevis, elongata, irregulariter in spirum convoluta vel glomerata, 

 antice ampliata, tumida, striis transversis subrugosis.
