 Common in mud and sandy mud, near low water mark. 



Fam. AMMOCHARID^. 



AMMOCHARES Oruhe. 

 Only one specimen belonging to this genus was found, 

 and that having only a few anterior segments, not suffi- 

 cient for identification.

PL. IX, FIGS. 133-136. PL. X, FIGS. 137-139. 



Body stout, diameter decreasing regularly from the 

 first segment. Operculum surrounded at base by a series 

 of conical papillae. On the dorsal surface the inner papilla 

 on each side is flattened at base, and between it and the 

 operculum are a few golden setae, curved to follow the out- 

 line of the opercular base. 



The tentacles have the usual structure, are white, with 

 sometimes a red or purple tinge. 



First segment not visible above, represented below by 

 two rounded lobes and two setigerous processes or ventral 

 rami. The lobes are placed one on each side of the mouth ; 

 outer margin convex, inner margin concave. In life they 

 are continually in motion, being alternately straightened 

 or moved from the mouth, and curved inward to the mouth. 

 Just outside of these lobes is a conical process, arising 

 from a swollen irregularly shaped base. On the outer 

 surface of the base is a curved depression, from which a 

 series of setae arises, similar to f. 139, but with the lateral 

 appendages much longer than in that figure. The setae 

 and the process itself point downward.
