iiules. They are mainly remarkable for the stoutness of their articuli 

 and the length and straightness of their dactylopodites. The 6th. 

 and 7th thoracic appendages are of very peculiar structure, and 

 have already been shortly described in the generic diagnosis. They 

 are similar in general form, but the 6th is somewhat the larger, its 

 excess of length being gained mainly in the basipodite. Each carpo- 

 podite forms a stout cylinder, armed at its point with a short, stout 

 spine, and densely clothed at its apex and outer aspect with short stout 

 recurved hooks. The propodite is articulated a little below the 

 middle of the outer and anterior aspect of the carpopodite, and the 

 dactylopodite forms a small, but much curved hook. The 8th thoracic 

 appendage differs considerably from any of the other appendages, and 

 is more of the normal type. Subequal to the second gnathopod 

 in length, it is the slenderest of all the appendages, the basipodite 

 alone being of any size, and even this considerably tapered distally. 

 All the thoracic appendages are somewhat hirsute. 



The first three ahdominal appendages, though of the usual type, 

 are very small and much broader than long. The fourth is the larg- 

 est of them all, its peduncle being stout and armed with a few stout 

 spines, and its rami, which are equally stout, about half the length 

 of the peduncle and armed with a number of stiff slightly curved 

 spines. The articulations of the rami of this appendage with its 

 peduncle are strong and of hinge type ; and watching the animal 

 while alive, I was impressed with the idea that the organ could be, and 

 probably is, employed by the animal as a forceps for holding on to its 

 house. Of the fifth abdominal appendage I have been unable to obtain 

 a satisfactory view. It is small and its peduncle is very short, though of 

 considerable breadth. The ramus appears to be single and rounded, 

 and has its end beset with recurved hooks, similar to those on the car- 

 popodites of the 6th and 7th thoracic appendages. The last abdominal 

 appendage is short and blunt and has no ramus, its end being armed 

 with a few spines, some of which show a tendency to hooking.

 This very beautifully ornamented species was obtained in the drift 

 net, in the middle of the Bay of Bengal, on a voyage from Chittagong to 

 Madras. Although so far from land, there was a certain amount of 

 flotsom and jetsom to be met with on the surface, and it was in the in- 

 terstices of such pieces that the little animal had its home. It builds no 

 regular tube, but constructs an irregular sort of shelter for itself by 

 glueing together tiny morsels of driftage, ekeing out its materials ; 

 from the appearance of some of the irregular masses resulting from its
