8 PROCEEDINGS OF THE NATIONAL MUSEVM. vol. xxxi. 



The whole surface of thebodj^is granulated and covered with minute 

 hairs, which increase in number and leng-th on the abdomen and the 

 edges of the uropods, where thej form a thick fringe. The color 

 light brown. 



This species can not be identitied with Cymodoce jjlUmi Edwards'^* 

 from the Mediterranean, and from the "east and west coast of Algeria," 

 for it differs in a number of points. The surface of the entire bod}^ 

 is granulated, while in Milne Edwards species only the posterior half 

 is covered with granules. There is no elevation at the extremity of 

 the longitudinal groove, as in C. pilom^ as described by Edwards and 

 figured by Lucas.'' Moreover, two tubercles are found on either side 

 of the groove in the j:) resent species, while in C. p'dvm there is but 

 one mentioned and figured. Lastl}", the uropods do not extend a great 

 deal beyond the extremity of the abdomen, as in C. 2)'dosa^ but reach 

 the extremit}' o\\\y. It differs also from Cymodoce aculeata Haswell in 

 the different arrangement of the tubercles on the terminal abdominal 

 segment. The species is founded on three specimens, all males, from 

 Hakodate Bay, Japan, which are in the collection of the U. 8. National 

 Museum.

CYMODOCE AUSTRALIS, new species. 



Body ovate, 3 mm. : (> mm. 



Head wider than long, with the front marginate and produced in a 

 small, median point. The e3'es are large, composite, and situated in 

 the post-lateral angles. The first pair of antenna3 have the first article 

 oblong, longer than wide, and produced at the outer distal angle in a 

 small truncate process; the second article is small, oval in shape, about 

 one-third as long as the first; the third article is narrow, elongate, 

 about one and a half times as long as the second. The flagellum is 

 composed of about fifteen joints. The first antennae extend to the 

 posterior angle of the first thoracic segment. The second pair of 

 antenna% with a fiagellum of about seventeen articles, extend to the 

 posterior margin of the third thoracic segment. 



The first segment of the thorax is longer than any of those following 

 and has the post-lateral angles produced backward. All the following 

 segments are crossed transversely by a carinated ridge. The epimera 

 are not distinctly separated, but faint lines of depression indicate the 

 place of coalescence. The lateral parts of the segments have the 

 posterior angles produced in narrow pointed processes directed 

 posteriorly. 



The abdomen is composed of two segments and is broader than the 

 thorax, although dorsally it does not show any increase in breadth.
