by the last pereioual segment; it equals tlie fiftli in length. 

 The second segment is half the length of the first. The third 

 and fonrth a little longer, equal. 



The urns is shorter than the pleon (23 : 24) and broader 

 thau long (28 : 23), subacute, feebly crenulated, fringed with 

 long plumose hairs. 



The uropoda (Pl. II. fig. 16) equal the urus in length; 

 the process of the peduncle is very long, obtusely pointed 

 The oiiter ramus is elongate-ovate, fringed with long plumose 

 hairs. The inner ramus is longer and broader, the posterior 

 margin rounded, crenulated, with short sharp spines; the whole 

 ramus is fringed with long plumose hairs (Pl. II. fig. 17); 

 the exteriör margin is slightly incised. 



The colour is red with oblong white spöts; there is no 

 larger darker spöt on the dorsal side of the fifth segment as 

 stated in the description of Schioedte and Meinert. The lower 

 parts of the sides of the first, second, third, and fourth seg- 

 ments are bordered with dark violet ; on the fifth segment there 

 is no trace of such a dark colour, but on the sixth and 

 seventh pereional segments, and on all the pleonal segments 

 it reappears ; at each corner of the anterior margin of the urus 

 there is also to be seen a dark violet spöt. The three first 

 epimerals have the same colour, the three last ones are only 

 partly spotted with violet.

Among the crustaceans in a collection which I bought 

 1877 of the naturalist-merchant Wessel in Hamburg there are 

 also two Rocinela, a male and a female, that are identical, I 

 think, with Schioedte and i\Ieinert's new species Rocinela 

 maculata. As only the male is hitherto known and described, 

 it seems very fit to give here a short description of an ovige-
