See also Asp. Novce Hollandice, Chenu, t. 4. f. 8 ; very like A. 

 Recluzianum, from gravel, with the fringe destroyed. 



The AspergiUum zeluensis (Chenu, t. 3. f. 3), in Mr. Cuming's 

 collections, has the tube covered with fine sand, and it is nearly 

 allied to A. clavatum ; but the disk has only two or three large 

 tubes on each side of the central slit.

6. Foegia. 



Umbo more or less covered with a swollen prominence in front ; 

 the whole of the valves except the umbo or nucleus enclosed in the 

 tube ; fringe indistinct, formed like the hole in the disk, of short 

 thick separate tubes. The animal unites sand, stones, &c. to its 

 tube.

ilia-, which are covered in the specimens from which he t"<>k hi- 



figures, so that I cannot depend on ins accuracy in this respect.
