somewhat produced; that of tlie peuultiraate pair (fig. 9) is considerably 

 broader in its proximal part than at tlie end, being expanded above to a 

 rounded lobe edged with about 4 bristles. The basal joint of the last pair 

 (fig. 10) is considerably broader than that of the 2 preceding pairs, being 

 greatly expanded posteriorly, with the edge of the expansion fringed with 

 several strong bristles, and almost angularly bent below the middle. 



The 2 anterior pairs of ui'opoda (figs. 11, 12) have the rami subequal 

 and linear in form, each being tii>pcd by a mnnber of spines, one of which 

 is more elongated than the others. The inner ramus has besides a small la- 

 teral spine about in the middle of the upper edge; otherwise the rami are 

 quite smooth. 



The last pair of uropoda (fig. 1 3) do not attain the length of the uro- 

 some, and have the inner ramus very small, with a minute apical spine 

 accompanied by 2 small hairs. The outer ramus is comparatively broad and 

 flattened, though tapering distally. It is devoid of ciliated set;e, but has on 

 the outer edge 3 fascicles of spines accompanied by a few simple bristles, 

 and on the inner edge 2 similar fascicles. The terminal joint is rather small 

 and narrow conical in form, being surrounded by several spines and bristles 

 issuing from the end of the proximal joint. 



The telson (fig. 14) is comparatively short and broad, nearly semicircu- 

 lar in outline, each half being armed with 3 slender lateral spines and a 

 single apical one accom2)anied by 2 small hairs. The cleft is very narrow, 

 and as usual extends to the very base of the telson. 



The adult male (fig. 15) is a little larger than the female, attaining a 

 length of 7 mm. 



In the general form of the body it does not differ much from the female, 

 though, as usual, somewhat more slender and compressed, and having the coxal 

 plates shallower. 



The superior antenna? are nearly of same appearance as in the female, 

 whereas the inferior ones (fig. 16) are very markedly distinguished by a 

 dense clothing of extremely delicate and slender sensory bristles, arranged 

 in several fascicles along the posterior edge of both the peduncle and the 

 tlagellum, giving these organs a brush-like appearance. 



The gnatliopoda (figs. 17, 18) are much more strongly built than in 

 the female, and nearly equal both in size and structure, exhibiting an aspect 

 rather similar to that met with in the males of the genera Gmclina and 

 AmatUlUna. As in those genera, the propodos in both pairs is very large 

 and almost clavate in shape, with the palm much shorter than the hind mar- 

 gin and slightly concave, being defined below by a somewhat projecting cor- 

 ner armed with 2 strong spines. The dactylus is rather strong and curved,
