To jndgc from the drawing given by Dana 1. c. pl. 68, fig. 2a, and 2(? (fig. 1 and 4 

 above), the form of the second pair of per«opoda is very peculiar, the carpus being not 

 dilated, much narrower than the carpus of the first pair. In the description, however, 1. c 

 p. 988 and 989, Dana says nothing about the different shape of the both pairs. Thus 

 it must be left to futui'e investigation to clear up this question. 



Dana's description contains further: 



The head is nearly filled with the pigment of the eyes; the head is higher than 

 half the length of the pertBon. The antennary area on the front of the head is small, 

 not half the height of the front. 



The antennce are short, subeqnal, hardly as long as half the height of the head, 

 subulate, extremity very closely multiarticulate. 



The epimerals of the first to third, and fifth to seventh pairs are small, trun- 

 cate below. 



The fir.<it. two pairs of perceopoda have the femur broad, lameliar. The geriu and 

 tibia are small, not produced. The carpus is broad, more than twice as long as the 

 tibia, and longev than the metacarpus and dactylus together. The dactj'lus is small. 

 The first two pairs are much shorter than the foUowing pairs, quite pubescent.
