second segment narrower, but slightly longer than the first, third segment laterally produced, 

 but the horns do not reach as far outward as the first segment, following segments all distinct, 

 gradually increasing in length, terminal one equilaterally-triangular. The surface of the abdomen, 

 like the sternum, is granulate. 



The colour of the animal is a greyish-white, the hairs are colourless. 



A single 9 of this species was formerly collected on the reef at Fadifolu Atoll, Maldives; 

 the "Siboga" obtained two cT from a depth between 54 — 90 metres at the west coast of Flores. 



Whether Alcock's specimen, the locality of which is not stated, is identical with the 

 present one, is impossible to make out.

It is with some hesitation that a new species is established for the single 9 obtained, 



as this is most closely related to the preceding species, but the following points are of importance. 



i" The carapace is granulate in a much less conspicuous way, the granules being less numerous 



and especially not sharpened and prominent towards the margins. The grooves defining the 



regions, as far as they are visible, present exactly the same course, but are much less 



distinct. The lateral margins are entire in the middle, not notched, the postero-lateral margins 



are somewhat concave. The surface of the front is clothed with a dense tuft of feathered 



hairs, w-hich are longer than those on the eye-stalks or on the antero-lateral margins of the 



carapace. Eyes are completely absent, not even a speek of pigment is to be 



observed. On the other hand the shape of the front, of the antennulae and antennae (fig. \a) 



and of the external maxillipeds exactly agree with what is found in T. /lirsiifus. The middle 



of the anterior margin of the buccal cavity is not thickened, and its lateral margins are 



convergent backward, quite like in Borradaile's fig ure of the 9 of "'Caeco- 



pilummis' hirsutus. 



2" The chelipeds are like those of the preceding species, but the subdistal tooth at the anterior 



margin of the meropodite is larger and more ridge-like. 

 3" The walking legs, especially the propodites, are broader, the propodites of the last 



pair (fig. \5) being even broader than long. 

 4" The first segment of the abdomen of the 9 covers the last sternal segment. 



It may be, that the dififerences enumerated are only due to sex, but Borradaile's 9 of 

 "" Caecopilummis" hirsittus presents a closely-granulate carapace, with the various regions as 

 well and as sharply defined as in the cf ; further, eyes are figured and the shape of the walking 

 legs agrees on the whole with what I found in the cf of Borradaile's species. But the outline
