1090 TEREDO. 



This shell is stated to be seven inches long, and appears by 

 Kaemmerer's figure to be four or five lines in diameter at 

 one end, which is nearly twice as broad as the other ; it is 

 ■white, sub-pellucid, taper, transversely wrinkled, and consi- 

 derably curved irregularly ; the aperture is said to be oval 

 and divided by a partition in the middle. 



CLAVA. 4. Shell with one end club-shaped, and the 

 other narrower, incurved, obtuse, and per- 

 forated in the middle.

Shell nearly two inches long, and about half an inch broad at 

 the lower extremity, from which it tapers upwards, and the 

 other end is said to be narrower, obtuse, somewhat incurved, 

 and perforated ; it is generally found in clusters, and is more 

 or less flexuous, of a brownish colour, with the outside rough 

 and the inside smoolh. I have in this instance quoted Walch 

 and Spengler on the authority of Schroeter, and Guettard 

 on that of Lamarck. Besides F. cornicula and F. gregata, 

 which are above noticed, Lamarck in his Systeme des Ani- 

 maux, has given the following notices of two other Fistulanae, 

 and he Pillon of Favanne, i. p. 672. t. 5. f. K, may pro- 

 bably also belong to the same natural family :
