PARASITIC CRUSTACEA FROM BIMINI — PEARSE 



351 



Anisotremus virginicus (Linnaeus), eight from the gills of mar- 

 gatefish, Haemulon alhidum Cuvier and Valenciennes, three from 

 the blue-striped grunt, Haemulon sciurus (Shaw), and nine from 

 the barred grunt, Conodon nobilis (Linnaeus). One male was col- 

 lected from a gill of a margatefish. 



Remarks. — This species is like Wilson's (1913) L. fondeus and 

 L. spiculatus. It differs from the former in the size of the dorsal 

 plate and from the latter in the lack of frontal lobes and the shape 

 and the armature of the mouth parts and legs. It differs from 

 Steenstrup and Lutken's (1861) L. konigii in the shape of the ceph- 

 alothorax and the dorsal plate, in the shape of the abdomen, and 

 the smaller size of the fifth legs. It is unlike Heller's (1868) L. 

 lativentris in the shape and the size of the dorsal plate and the 

 cephalothorax ; and from his L. nobilis in the same manner. The 

 name refers to the wide dorsal plate. 



LERNANTHROPUS BIPIDUS, new species 



Figures 70, b-e; 72, a-<i 



Female. — Color cinnamon-brown. General form rather stocky. 

 Cephalothorax longer than wide, with two lateral anterior lobes, 

 the anterior one-half narrower than the posterior. Next two seg- 

 ments separated by distinct dorsal and lateral grooves. Dorsal 

 plate is cleft through half its length (hence the name, bifidus) and 

 the lateral lobes overlap somewhat; about as wide as long; wider 

 than preceding segments. Abdomen and genital segment wider
