18 CARL BOVALLIUS, NEW ISOPODA. Til. 



The hodji is elliptical, almost three times longer than broad. 



Tlie head is broad, as broad as a third of tlie bredtli of 

 tlie fourth pereional segment; the anterior margin is straight. 



Tlic eyes are distinct, elongate-ovate. 



The lirst pair of antennce are a little compressed; the se- 

 cond pair are longer, a little more slender, feebly compressed. 



The posterior corners of the fourth and fifth pereional 

 seements are truncated.

The femora of the last foiir pairs of pereiopoda are not 

 carinated; the seventh pair are much longer than the pre- 

 eeding pairs. 



The first segment of the pleoii is partly obteeted, the 

 four succeeding are subequal in length. 



The urus is smooth, rounded. 



The rami of the uropoda are subequal in length, elongate- 

 ovate. 



Anilocra guinensis is most nearly allied with A. co.ralis, 

 ScHiOEDTE and Meinebt, but differs by the truncated corners of 

 the fourth and tifth pereional segments, the not carinated femora 

 of the last four pairs of pereiopoda, the form of the urus, a. o. 



Ovigerous female.

Tlie hodi) is transversally convex, the surface smooth and 

 härd. 



The head is broadly triangidar, truncated in front, broader 

 tlian long (11:8); the frontal margin is straight, the surface 

 smooth, feebly convex. 



The eyes are small, longitudinally ovate, distant by more 

 tlian half the bredtli of the head; they are not prominent. 



The fivst pair of antennce (Pl. IV, fig. 48) are eight-jointed, 

 with distinct peduncle, a little compressed, the second joint 

 tlie longest, the first a little broader. They reach to the anterior 

 margin of the first pereional segment. 



The second pair (Pl. IV, fig. 48) are a little longer and 

 narrower, nine-jointed, less compressed. The sixth joint is the 

 longest; they reach beyond the midth of the first pereional 

 segment. 



The lahrum is broad, rounded. 



The inandlbles are strongly built but narrow, the free end 

 is rectangularly bent, not spirally, ending in a sharp, flat
