base by a constriction. The antennular peduncles are very 

 thick in their whole length; the dorsal protubérance of first 

 joint is richly adorned with long setas and produced above along 

 the inner side into a lobe, the shape of which is seen on fig. 20; 

 the outer distal angle of first joint has a short conical process. 

 From the distal inner angle of 

 third joint two very long and 

 thick setas proceed; basai part 

 of lower outer flagellum is 

 strongly thickened and fur- 

 nished with a very long and 

 extremely dense and thick tuft 

 of thin setœ. The antennal 

 squama with a denticle on the 

 outer distal angle. Abdominal segments without dorsal 

 spines, but fourth, fifth and sixth segments each with 

 a keel in the posterior part of the mesial line and [besides 

 with the major part of the limit between the upper 

 surface and the sides distinctly carinate. Endopod of uropods 

 somewhat shorter than telson and slightly shorter than the 

 exopod. — The maxillulse essentially as in T. inermis, but the 

 outer plate from the proximal lobe is very small, much smaller 

 than in the former species and far from reaching the outer 

 margin of the joints. — Length 44 mm . 

 Locality. — Stat. 1749, 1 spécimen. 



Remarks. — This species is allied to T. insignis, but 

 according to the shape of the front end of carapace, a sharp 

 différence in the structure of the maxillulas, etc., it can not 

 be the maie of that species. The species is very beautiful : 

 the front half of the carapace and the mouth-parts are deep 

 purple, the posterior half of carapace lighter purple, besides 

 the upper side of the antennular peduncles, transverse bands 

 on the abdominal segments, oblong spots above the branchial, 

 the anterior surface of the anterior thoracic legs, etc., are also 

 purple.
