540 ME. E. I. POCOCK ON THE 



Legs imperfect. 



Measurements in millimetres. — Total length 27 ; carapace, 

 width 11, median length 7'3, distance between eyes 4. Chela : 

 length of femur 6"7, of tibia 9*5. Legs : femur of 1st 16*5, 2ud 

 12, 3rd 12-5, 4th 11-8. 



Locality of type unknown; of a second smaller example, 

 belonging apparently to the same species, Cuba. 



The Cuban example, measuring 11 mm. long, with the cara- 

 pace 7 mm. in width, appears to differ from the type merely in 

 having the chelse shorter, and therefore the spines closer 

 together, and in having the external surface of the tarsus 

 normally smooth. 



In its character this species seems to lie between T. scalra 

 and T. latifrons. From the latter it differs in having the lateral 

 eyes less widely separated, the frontal border of the carapace 

 narrower and more coarsely dentate, in the presence of 8 spines 

 on the upper edge of the tibia of the chela, in the coarser granu- 

 lation of this segment, &c. From T. scahra, T. Keyserlingii 

 diflfers in having the median tubercle further from the anterior 

 border, the lateral eyes more widely separated, the 1st spine 

 on the tarsus of the chela smaller, and no spinule at the base of 

 the 6th spine on the upper edge of the tibia. 



This is very likely the Cuban species that is figured as Phrynus 

 2)ah?iatus by Eamon de la Sagra. 



Tarak^tfla vieidiceps, sp. n. (PI. XV. fig. 8.) 

 Colour (? young). Carapace and femora pale olive-green; 

 abdomen darker, adorned with a pale spot marking each mus- 

 cular impression, and one in the middle ; mandibles, chelae, 

 tibise, and tarsi of legs ferruginous, the articulations on each side 

 of the two principal joints of the legs of the 1st pair, i. e. 

 between the femur and tibia, and the tibia and tarsus, yellow. 



Carapace sparsely granular, with its frontal portion gently 

 sloped downwards and forwards ; the distance between the eyes 

 l6ss than half the median length of the carapace, and about 

 twice the distance between a lateral cluster and the anterior 

 edge, which is greater than the distance between the eye-cluster 

 and the lateral edge ; the median tubercle trausverse, separated 

 from the anterior margin by a space which equals nearly twice 

 its longitudinal diameter ; the anterior border mesially emar- 

 ginate, with rounded lateral lobes, armed with about five teeth
