 Terebratula. Enc. Meth. t. 243. f. 10. 



Inhabits the Mediterranean. Chemnitz. 



Shell about five lines long and six broad, of a pale reddish 

 brown colour ; the flat truncated valve on the inside has 

 three longitudinal ribs, and the other which is convex, is 

 striated and divided by a partition in the middle ; the flattest 

 valve is so much truncated as to be almost semicircular, and 

 the umbo of the other, which has the perforation, is promi- 

 nent. 



pubescens. 20. Shell ob-ovate, downy, longitudi- 

 nally grooved, and has the umbo in one valve 

 prominent and gaping.

 Guatter, t. 96. f. C. 



Inhabits the Norwegian Seas on corallines. IAnnaus. 



Linnaeus says the shell is about the size of a cucumber seed ; 

 white, and covered with very minute erect distant hairs ; the 

 valves are nearly equal, and neither is truncated, but the 

 umbo which has the perforation, is more prominent than the 

 other. Muller's Terebratula pubescens appears to be Ano- 

 mia Caput-serpentis, covered with a minute hairy Zoophyte. 



sanguinea. 21. Shell ovate, glabrous, with one 

 valve longitudinally keeled, and the other de- 

 pressed in the middle, and the perforated 

 umbo more prominent than the other.

 Anomia, No. 10. Schroeter Einl. iii. p. 411. 



Inhabits the East Indian Seas. Chemnitz. 



Shell nearly seven lines long, and about five broad, of a pale 

 reddish colour with darker sanguineous rays, and rather pel- 

 lucid ; the perforated summit of the convex valve is more 

 elevated than the other, but neither is truncated. I have a 

 specimen which Mrs. Mawe told me came from the South 

 Seas. 



caput-serpentis. 22. Shell ovate, longitudinally 

 grooved, with the summit of the convex valve 

 elevated and perforated ; margin sinuous and 

 crenulated.
