the anterior maroin that is notched in the middle, is armed at either angle with a sharp spine 

 which is directed straight forward and the lateral margins carry anteriorly a lateral process, 

 terminatino^ in two teeth, the anterior of which is pointed and curved baclcward, whereas the 

 posterior is also acute, but directed obliquely forward.

 I young male. 



This specimen is nearly 35 or 36 mm. long, the carapace, rostrum included, is 12 mm. 

 long and, without it, 8 mm.: it is apparently not yet adult, because the two branches of the 

 petasma are not yet united. It agrees very well with Bate's figure 4. The rostrum that reaches 

 nearly to the end of 3"^ antennular article, is slightly turned upward, rather slender and somewhat 

 narrowing distally ; the upper margin is a little concave, the lower a little convex. The rostrum 

 bears 3 teeth, the foremost tooth is a little farther distant from the penultimate than from the 

 acuminate tip, which is slightly curved downward; the lower margin bears one sharp tooth, 

 that is directed straight forward and situated immediately in front of the foremost tooth of the 

 upper margin and between this tooth of the lower margin and the tip of the rostrum there is 

 still another smaller tooth, immediately below the tip. The post-rostral carina is armed with 

 5 teeth. The 8 teeth with which the upper margin of carapace and rostrum is armed, are 

 equidistant and gradually decrease in size from the hindmost to the foremost. The carapace 

 which is tomentose and here and there pilose, carries a few wrinkles or ridges. Interrupted 

 wrinkles and a ridge run between the strong hepatic spine and the posterior margin of the 

 carapace, defining the branchial region superiorly, and four or live other longitudinal wrinkles 

 are seen immediately above them on the lower part of the cardiac region ; one observes, 

 finally, an oblique wrinkle near the postero-lateral angles of the carapace, that runs nearly 

 parallel with the lower margin. 



The abdomen fully agrees with Bate's figure 4, as regards the number and the arrangement 

 of the sharp teeth with which the pleura are beset; I will, however, observe that the elevated 

 parts of the i"', 2"<ï and 3"! somite are transversely wrinkled and rugose, and that these 

 wrinkles gradually become less distinct on the following somites. The small oblique tooth on 

 the 1^' somite is deeply cleft. 



The external maxillipeds, the joints of which are flattened, just reach to the end of the 

 antennal scales. The thoracic legs of the r' pair bear at the far end of their 2°'i and 3'''i joints 

 a rather small, sharp tooth, a similar tooth occurs at the base of the 2°'^ legs, but their y^ 

 joint is unarmed like also the legs of the 3"' pair. In all the chelate legs the fingers
