figs. 9 & 10). Inner basal angle of coxa of pedipalp and apical 

 half of labium numerously spinulose. 



The female is similar in general characters, the legs being more 

 numerously spinose. 



The protarsi of the pedipalp have a pair of spines on the inner 

 side, a little before the middle, and four spines ranged round the 

 apical margin on the inner side and beneath. 



The protarsi of the first pair of legs have a pair of spines at 

 the apex beneath, a smaller one on the outer side, and another in 

 the centre towards the base beneath. The tibiae and protarsi of 

 iii. and iv. are numerously spinose. 



This species, of which four adult males and several females were 

 taken by Dr. luce, appears to be a fairly common Spider in 

 Trinidad. Other examples have been received from Messrs. Beaven 

 Rake and Thomas Potter from the same Island. 



The last-named gentleman has very kindly ascertained for me 

 the habits of these small Theraphosids, which burrow in the 

 ground somewhat after the fashion of Eurypelma. He says : — 

 " The hole made by this spider is not lined with silk, so far as I 

 can see ; and if it is, the coating must be very thin and almost 

 imperceptible. The direction of the burrow is generally at an 

 oblique angle with the surface of the ground. Sometimes the hole 

 is straight for a short distance, but it always winds about, and is 

 more often irregular in direction, like a crab's hole. 



" The earth removed by the spider is nearly always thrown away 

 from one side of the aperture in a little mound of coarse pellicles 

 of mould. The specimen I sent was taken from a burrow about 

 ten inches deep and from five-eighths to three-quarters of an inch 

 in diameter. I had two specimens taken from burrows near to 

 each other, and, unfortunately, in captivity the larger spider, being a 

 cannibal, devoured her weaker fellow prisoner." (PL LIV. fig. 12.)

2 . Total length 30 mm. (approx.). Carap. 12 long, 10 lat. 

 Legs : i. 38— ii. 3.5— iii. 33— iv. 46. Protarsus iv. 11. Tibia iv. 8-5. 



Colour. Carapace bright orange-red, clothed with short silky 

 yellow hairs. Legs, palpi, and abdomen pale coffee-brown, clothed 

 with fine lighter brown hairs. Sternum and coxae of legs pale 

 rufous brown. 



Structure. In general characters similar to that of the type of 

 the genus, S. ravidus E. S., from A^enezuela. It differs, however, 

 in the spinulatiou of the tibiae of the first two pairs of legs. 

 Tibia i. has two spines in a longitudinal row beneath, and one 

 spine on each side of the apical margin beneath ; (ravidus has four. 

 sec. Simon). Protarsus i. has two spines in a longitudinal row 

 towards the base beneath, and one at the apex beneath.
