The eyes do not nearly fill the very wide orbital sinuses. 

 Besides the small part of the eye, Avhich projects into the sinus, 

 the larger posterior part can be seen as a dark yellow body, 

 through the transparent carapace, and on the external side of 

 this there is seen a bud or tubercle which represents the lateral 

 process of the eyestalk of the adidt. 



The antennules are merely rudimentary and very short. 

 No spine is developed at the outer angle of the basal peduncular 

 joint, and the scale is represented by a short, blunt process. 



The antennae are also very small. The scale is very feeble, 

 but the renal tubercle is comparatively well -developed. 



The first four pairs of oral appendages are similar to those 

 of the adult. 



The second and third maxillipedes have each a large exopodite, 

 which is quite absent in full-grown specimens. In the second 

 maxillipedes it is about two and a-half times as long as the 

 endopodite, and in the third maxillipedes the two are about 

 equal in length. The exopodite in both cases ends in a tuft 

 of long setae. 



There are only two pairs of pereiopods developed, but these 

 are large and well formed. Each bears an exopodite ending in a 

 group of long setae. These exopodites are formed of two joints, 

 which are of equal length. 



The first pereiopods are not relatively so long as in the adult, 

 and the sutures between the various joints are not easily seen, 

 especially in the proximal part of the limb. Near the distal 

 end, and on the outer side of the merus, there are two strong 

 spines. The carpus also bears two large spines, one proximal 

 and one distal. The propodite is large and massive, the palm 

 slightly shorter than the fingers. The exopodite is shorter than 

 the propodite. 



The second pereiopods have four very long spines on the merus, 

 two near the middle, and two at the distal end. These spines 

 are longer than the joint which bears them. The carpus has 

 two spines of which the distal is the longer. The palm of the 

 propodite is loiiger than the fingers. The exopodite is longer 

 than the propodite. 



The pleopods are formed, but are not functional as yet ; they 

 are very small and have no setae. There is a mere tubercle 

 indicating the position of the appendix interna. 



The uropods are shorter than the telson and are very feeble. 



Size. — ^The specimen measured from tip of rostrum to end 

 of telson, when the abdomen is straightened out, is only 

 7 m.m long. 



The single specimen was taken at the following station : —
