AETHEOPOD FAUNA OF THE WEST INDIES. 539 



than the protarsal ; the third tibial about twice the length of the 

 second, which is about a third of the distance between the eyes. 



Measurements in onillimetres . — Total length 17'5 ; length of 

 carapace along middle 8, width 12"5, distance between lateral 

 eyes 5. Chela: height of femur 2*9, length 7, of its longest 

 spine 2 ; width of tibia 3*6, length 9"5, of longest spine 2*5. 

 Legs : femur of 1st 17, of 2nd 12, of 3rd 13, of 4ith ll'S ; tibia 

 of 2nd 12, of 3rd 15-5, of 4th 12.

This species, perhaps, approaches nearer to T. Goesii of 

 Thorell than any known to me. The two seem to have the 

 lateral eyes somewhat similarly placed, and in the last pair of 

 legs the second and third tibial segments seem to bear the same 

 proportion to one another. But Dr. Thorell, unfortunately, does 

 not mention many of the characters upon which I think stress 

 should be laid. His species, however, seems to differ in several 

 points of measurement ; for instance, the protarsus of the 4th 

 leg is about one-third the length of the tibia (it is almost one- 

 half the length in my species), and the tibia is considerably 

 longer than the femur, whereas in my species the two segments 

 are almost equal. 



Taeantula Ketseelinq-[i, sp. n. (PI. XL. fig. 7.) 



Colour a uniform black. 



Upper surface coarsely granular. 



Carapace : distance between eyes greater than half the median 

 length of the carapace ; distance between each lateral eye-cluster 

 and anterior border equal to half the distance separating the eyes, 

 and much greater than the distance between the eyes in question 

 and the lateral border ; median tubercle transverse, separated 

 from the anterior border by a wide space, which equals at least 

 twice its longitudinal diameter. Anterior border lightly emar- 

 ginate, coarsely dentate at the sides, concealing the frontal 

 process. 



Chelas long, both tibia and femur coarsely granular above, 

 robust ; the tibia wider than its longest spine ; the spine-arma- 

 ture almost exactly the same as in T. harhadensis, but owing to 

 the greater length of the segments of the chelae the spines on the 

 femur and the superior proximal spines on the tibia are more 

 isolated ; moreover, the 1st superior tarsal spine is very minute ; 

 in its proximal half the tarsus is externally very distinctly 

 granular.
