GENUS STRIGILLA Turton 1822 



Surface arranged in two or three 

 sculptured areas in which the ridges di- 

 verge or otherwise; posterior end not 

 flexed; hinge as in Tellina.

 tured with regular parallel impressed 

 lines, no longitudinal striae, transverse 

 wrinkles minute. Length 11 mm.

 margin. It is striking on account of the 

 zigzag coiirse of the oblique sculpture 

 over it.

GENUS TELLIDORA Morch 1856 



Delicate white, compressed, shells 

 with a portion of the margin serrated. 



TELLIDORA CRISTATA Recluz. Left valve 

 flatter than the right, v;hile the reverse 

 is the case of the Pacific T. Burneti. 

 Length 25 mm. This exceptionally beauti- 

 ful form, with its saw-tooth edge, cannot 

 possibly be confused with any other. The 

 author dredged it alive in Tarpon Bay, 

 Sanibel. Dr. Perry has taken it there also 

 at low tide, the animal's position being in- 

 dicated by a small slit in the mud or sand.
