Genus 4. Stratiotes, nov. gen. 



Front with a distinct rostral projection. Ocular peduncles 

 long and slender, the basal scales small and situated close 

 together. Autennal acicle short and straight ; flagellum 

 ciliated. Chehpedes unequal, the left larger ; fingers moving 

 vertically, scarcely excavated. Penultimate pair of legs sub- 

 chelate. 



This genus appears to be allied to Diogenes, Dana, but the 

 latter is distinctly characterized by the movable rostriform 

 process situated between the ocular peduncles. 



Stratiotes setosus, nov. sp. Plate XXL, figs. 4-6. 



Pagurus setosus, Filhol, Miss, de I'ile Campbell, p. 490, 



pi. xlix., figs. 5-7. 



Carapace with the front less than half its width, slightly 

 produced into an angular point on the median line ; lateral 

 angular projections very slight, but defined by a short spine ; 

 sides of the front with a row of minute spinules ; surface with 

 tufts of hairs, especially on the sides. 



Ocular peduncles straight, cylindrical, quite smooth, nearly 

 as long as the whole width of the carapace ; basal scale pro- 

 duced on its inner side into a short spinose lobe. 



Peduncle of the antennules slightly longer than the ocular 

 peduncles. 



Peduncle of the antennae not reaching to the end of the 

 ocular peduncles; ultimate joint nearly naked; basal joint 

 transverse, with a minute spine on its inner edge and pro- 

 duced on the outer edge ; acicle lanceolate, very acute, reach- 

 ing beyond the penultimate joint of the peduncle, with one or 

 two spines near its base and numerous hairs on its surface 

 and margins ; flagellum reaching to the extremity of the right 

 chelipede, furnished with a thick fringe of setae. 



Chelipedes very unequal, left much the larger. 



The right chelipede has the meros sharply keeled above, 

 ending in a sharp spine, outer and inner faces nearly quite 

 smooth. The rest of the limb is covered, especially on its 

 upper edge and outer side, with long densely tufted hairs, 

 while the inner side is nearly smooth. The carpos, propodos, 

 and dactylos are subequal in length, and their upper edge 

 bears a row of strong spines, which diminish in size towards 

 the end of the finger. 



The left chelipede is very strong. The meros has a few 

 strong spines on its distal upper edge and on both its lower 

 margins. The carpos is short, with a rounded upper and 

 outer side, furnished with numerous spines, which are espe- 

 cially strong on the upper margin, and are more or less hidden 

 by short thick hairs, which are especially numerous towards
