lobes are acute. The uropoda are short, not longer than half the length 

 of the terminal segment of the body; the basal segment is broad, 

 quadrate in shape, and shorter than either branch ; the 

 inner branch is somewhat longer than the outer one. The 

 middle piece of the operculum in the male is very similar 

 to the figure given by Sarsi of the type species of the 

 genus, Janiropsis breviremtis. It is produced and greatly 

 dilated at the distal extremity. 



Nine specimens were obtained by the Harriman Expe- 

 dition at Yakutat, Alaska. They were collected by T. 

 Kincaid, after whom the species is named. Five females

(X 77)- and four males were collected. The legs of the first pair 



in the male are not greatly longer than the others; they are longer in 



the type species of Janiropsis,

The very short superior antennae with few articulations, the greatly 

 dilated joints of the max- 

 illipeds, the form and 

 shape of the middle piece 

 of the male operculum, 

 with its dilated tip, and 

 the shortness of the uro- 

 poda, which are only half 

 the length of the termi- 

 nal segment of the body, 

 are characters which un- 

 doubtedly place this spe- 

 cies with Janiropsis Sars.
