AETHEOPOD FAT7NA 01" THE WEST rtTDIES. 475 



Locality. Mustique Island, under decaying leaves ; St. YiDcent 

 (Ballein, north end of island), in bed of stream beneath sod, on 

 rock {H. m Smith). 



Class CHILO&NATHA. 

 Order LIMACOMOEPHA, PococTc. 



Pamily G-lomeeidesmid-s;, Latzel. 



Body consisting of 19-20 segments ; the segments subequal in 

 size and subsimilar in form, none of them being abruptly larger 

 than the rest, although they decrease in size from the middle of 

 the body to its anterior and posterior ends. 



Head convex and elongate from above downwards ; the an- 

 tennae moderately long, consisting of 7 subequal segments. 



Eyes apparently represented by a large circular depression 

 above and behind the base of the antennae * ; at the bottom of this 

 depression, along the posterior portion of it, is a curved series of 

 (4) colourless tubercles, which perhaps are ocelli. 



The mandibles well developed, apparently without the basal 

 segment or cardo ; the gnathocMlarium with a large T-shaped 

 sclerite representing the mentum and promentum; the lingual 

 lobes short and contiguous ; the stipites widely separated 

 throughout their extent as in Glomeris, each tipped with two 

 malae ; the bypostoma large and crescentic. 



JEach segment, except the last, consisting of a vaulted tergal 

 piece and a free pleura on each side. The first four furnished 

 with a single pair of legs each ; the rest with two pairs of legs, 

 except the last, which is apodous and is represented merely by a 

 tergal sclerite. 



No tracheal plates (pedal laminae) lying between the pleurae 

 and the bases of the legs. 



The legs^ including the enlarged basal segment, consist of 

 6 segments, of which the second, fourth, and fifth are short, the 

 third and sixth long. 



In the male the legs of the seventh segment are not modified 

 for copulatory purposes, but the last pair {i. e. the posterior pair 

 of the penultimate segment) are shortened, thickened, and capable 



* This organ seems to be the homologue of the horseslioe-Bhaped ' sensory * 

 organ of Glomeris.
