A species of small size, unless the two specimens are not yet full-grown, for they are 

 respectively only 39 and 37 mm. long. It belongs to that small section in which an epipod is 

 present on the 2°'^' maxillipeds only. The carapace with the rostrum measures one-third the total 

 length. Rostrum very short, reaching, just beyond the eyes, to the end of the i^' joint of 

 the antennular peduncle; in addition to the epigastric tooth, the rostrum bears in one specimen 8, 

 in the other 7 contiguous teeth, of which the i^' is situated on the carapace, the 2"^ immediately 

 before the frontal border, and which teeth reach to the tip. The characteristic form of the 

 rostrum may be recognized from the figure ; the rostral teeth progressively decrease in size 

 towards the tip and a line uniting their tips curves regularly downward, while the tip is slightly 

 upturned. Lateral ridge of the rostrum low, broad, regularly narrowing to the tip. The lower 

 marijin, which is frin^ed with lonsJ hairs, .shows its greatest width between the 2"^^ and the 

 y^ tooth ; it is emarginate at the base, while the rest appears slightly concave ; the epigastric 

 tooth, that is just as large as the i*' rostral tooth, is situated at the anterior third of the 

 carapace. No post-rostral carina. Post-ocular tooth small, sharp. Post-antennular (antennal) 

 tooth of moderate size, the buttress is little prominent and soon fades away backward; post- 

 antennular groove shallow. The longitudinal fissure that runs from the frontal border of the 

 carapace backward, is short, extending in one specimen as far as the epigastric tooth, in the 

 other even only as far as the hepatic spine; the transverse suture, above the y^ pair of legs, 

 is also short. Hepatic spine a little smaller than the post-antennular spine. Antero-inferior angle 

 of the caraj^ace rectangular, obtuse, not spiniform or dentiform. As in Parap. acclivirostris^ 

 the subhepatic ridge stops far short of the antero-inferior angle. At either side of the epigastric 

 tooth, also just behind the post-orbital tooth and furthermore in front of the subhepatic ridge 

 and of the hepatic spine, the carapace appears tomentose, but for the rest it is smooth and 

 glabrous like the abdomen. 



The four anterior abdominal terga are rounded, not carinate, though the 4"^ somite 

 is slightly compressed; 5''^ and 6* terga sharply carinate, the carina of the 6* ending in 

 a small tooth. Sixth somite one and a half as long as the 5''', half as long as the carapace 

 without the rostrum and just as long as the telson ; the telson that extends a little beyond 

 the middle of the inner uropods, is deeply grooved and ends rather acutely whereas the lateral 

 margins bear each 4 small spinules, the posterior of which is somewhat larger than the preceding ; 

 the two posterior spinules are situated much nearer together than the two anterior. 



The antennular peduncle (6,5 mm.), i. e. the distance between the frontal border of the 

 carapace and the tip of the peduncle, is about half as long as the carapace, the rostrum 

 included; the 3"^ joint measures two-fifths of the 2"'^; flagella subequal, the lower (5 mm.) being 

 very little longer than the other, and a little shorter than the peduncle. 



Antennal peduncle reaching as far as the eyes, a small spine at the infero-external 

 angle of its basal joint; flagella lost, antennal scales as long as the antennular peduncle. 



External maxillipeds hairy, stouter than the thoracic legs and reaching to the anterior 

 fourth or fifth of the antennal scales ; terminal joint measuring two-thirds the length of the 

 penultimate. 



The legs of the i'*' pair extend to the middle of the antepenultimate joint of the outer
