TELLINIDAE 429 



the pallial sinus runs directly posterior to the anterior muscle scar. Common 

 in shallow water in sand and commonly washed ashore. 



West Indian collectors should not confuse this species with Strigilla 

 rombergi Morch (southeast Florida, the Bahamas to Lesser Antilles) which 

 is very similar, except that the upper line of the pallial sinus does not reach 

 the anterior muscle scar. The radial cut lines are more numerous and more 

 curved in rombergi. Common.

Vz inch in length, oval, inflated, shiny, all white in color and with the 

 peculiar Strigillid sculpturing which is very similar to that in 5. pisiforinis 

 (the radial cut lines meet the ventral margin of the valves at an angle of 

 about 45 degrees). The pallial line runs forward from the posterior muscle 

 scar but does not reach the anterior muscle scar as it does in pisiforutis. 

 Common. Do not confuse with the larger Divaricella qiiadrisulcata (page 

 391) which has fine denticulations on the inner margins of the valves. 

 5. flexuosa Say 1822 is preoccupied by Montagu 1803 and Turton 1807, 

 and must take the name viirabilis Philippi 1841.

% inch in length, similar to 5. carnaria, but always much smaller and 

 more inflated. The pink color inside is concentrated in the deepest part of 

 the valve, and the margins are usually white. The radial, oblique cut lines 

 meet the ventral margin of the valve at about 45 degrees angle, while in 

 carnaria the Hnes are almost vertical. This is a very abundant species, es- 

 pecially in the Bahamas where they are gathered in great numbers and 

 brought to Florida for use in the shellcraft business.

/4 to I inch in length, elongate, concentrically and finely ridged. Char- 

 acterized by the strong crenulations on the posterior dorsal margin and by 

 the hghtly hooked-down posterior ventral margin. Color whitish with a 

 yellow or orangish tint. Moderately common from low water to 60 fathoms.
