The 111 a 1 e. 



The body is only a little nan-ower than in the female, the head and pei^seon to- 

 gether being soniewhat longer than the greatest breadth of the penBon, and neai"ly as 

 long as the pleon and urus together. 



The eyes occupy the whole surfaee of the head, and consist of an uruisually large 

 iinndier of ocelli. 



The first j3a«V of antennas reach to the hind margin of the second pleonal segment. 

 The first joint of the fiagellum is longer than the whole peduncle; the following flagellar 

 joints are subequal in length, slender, cjdindrical, and abont five times as long as broad- 

 The flagellar joints are twenty-four in number. 



The second -pair of antenrue are a little longer than the first; the fiagellum has 

 twenty-three joints, the first, the longest, being considerably longer than the last pedun- 

 cular joint. 



The perceon. The first three coalesced segments are nearly as long as the three 

 following; the seventh segment is about as long as the two preceding together. 



The epimeraU are as long as the under margins of the corresponding segments. 



The branchial säcks are very large, but shorter than the femora of the correspond- 

 ing pairs of perteopoda. 



The jirst pair of perceopoda. The femur is neaidy as long as the four following 

 joints together; it is broadest at the middle, and about three times as long as broad. The 

 carpus is much dilated; the front side of the carpal process is not fuUy half as long as 

 the hind margin of the metacarpus. The metacarpus is considerably longer than the 

 stem of the carpus; the front margin is strongly convex; the hind margin is serrated, 

 with spine-like, simple teeth. The dactylus is as long as two-thirds of the metacarpus^ 

 and is finely serrated on the hind margin. 



The second pair are not longer than the first, and reach nearly to the apex of the 

 tibia of the third pair. The femur is almost lineaT, more than three times as long as 

 broad, and fully as long as the four following joints together. The carpal process is 

 as long as the rest of the joint; its front side is as long as three-fourths of the hind 

 margin of the metacarpus. The metacarpus is much longer than the stem of the carpus, 

 and is armed as in the first pair. The dactylus is someAvhat more than half as long 

 as the metacarpus. 



The tJiird and fourth 'pairs. The femur is narrow, a little broader at the apex, 

 fully four times as long as it is broad at the apex, and considerably longer than the three 

 following joints together. The tibia is broad at the apex, quite as broad as the femur. 

 The carpus is much longer than the tibia: the hind margin is indistinctly serrated, and 

 carries two bristles. The metacarpus is about as long as the two preceding joints 

 together, and is longer than two thirds of the femur; the hind margin is serrated. The 

 dactjdus is nearly half as long as the metacarpus. 



The ffth, sixth, and seventh pairs are not longer than the two preceding pairs. 

 The femur is broadest at the apex, not full}' t\vice as broad as that of the third and
