above, its width about equal to the length of the "hand-back" which is 

 furnished with an oblique row of four piliferous pores. Digits short, 

 curved, in contact, the movable a little longer than the length of the "hand 

 back" the immovable furnished with five piliferous pores; four more of 

 these pores in a line on the external surface of the hand, lying between the 

 bases of the two digits. 



Legs smooth, exeept the inferior edge of the anterior two femora, 

 which are granular ; the distal tarsal segment with two rows of hairs 

 beneath. 



Pcctines short, furnished with 7 teeth (one specimen with eight.) 



Male : Slenderer than female, the tail longer, being about 4^ times the 

 length of the carapace. The upper surface of the hand very finely granular. 

 Pectines larger, the teeth much longer, 8 in number. 



Measurements in millims : Female total length 38, of carapace 5, of tail 

 20; width of 1st candal segment 3, length 2; length of 4th segment 3, 

 width 2.5, length of fifth 5.5, width 2.5 ; length of palp 15.5, width of 

 brachium 1.8, of manus 4, of "hand back" 3.8, of movable digit 4.5.) 



Male : Total length 31, of carapace 4, of tail 19. 



Locality: Trinidad (W. E. Broadway and J. H. Hart.) This species 

 is very nearly related to Chactas Gollmeri, Karsch from Caracas, which pro- 

 bably also belongs to the same genus. Karsch, however, makes no men- 

 tion of the presence of keels and granules upon the lower surface of the 

 4th caudal segment. Nor in Broteochactas nitidus is the manus marked with 

 many ocelliform punctures arranged in three rows. 



I also refer to this genus Chactas delicatus Karsch of which the British 

 Museum has a large number of specimens from Demerara (British Guiana) 

 a few ticketed South America, and one from Colombia. The variety 

 named opacus by Karsch is nothing but the male of delicatus. 



Pedipalpi. 



Very few species of this group have been recorded from the West 

 Indies, as may be seen from the subjoined list, and neither of these are 

 restricted in range to this area of the Neotropical Region. 



Tarantula reniformis (Linn.). 

 Phalangium reniforme, Linn. 



Colour : Carapace reddish brown or almost black, with some faintly 

 indicated lateral marginal flavous spots and some fine stripes of 

 the same colour radiating from the fovea externally and posteriorly ; upper 

 surface of the abdomen in well coloured specimens ornamented with black 

 or deep brown and reddish or flavous spots, the spots alternating like the 

 pattern of a chess-board, each tergite bearing 10 spots, 5 anterior and 5 

 posterior, the anterior row consisting of 3 black and 2 yellow spots and 

 the posterior of 2 black and 3 yellow spots ; palpi the same colour as the 

 carapace ; legs ferruginous or fuscous, with a faintly defined flavous spot 

 on the external surface of the femur. Lower surface ferruginous or 

 fulvous. 



Carapace coarsely but not closely granular, its anterior border lightly 

 emarginate and conspicuously dentate, the rest of the border denti- 

 culate. The upper surface of the abdomen granular like the carapace. 



Palpi rather short, but varying in length from about three times the 

 length of the carapace to only a little more than twice the length ; the 

 brachium a little longer than the humerus, longer than the length of the 

 carapace but shorter than its width. The humerus granular above and 

 below, more weakly granular in front, its upper edge armed in its prox- 

 imal half with from 5 to 6 (8) larger spines and some smaller ones ; the
