ARTHROPOD PAUIfA OF THE WEST INDIES. 531 



Tarantula tessellata, sp. n. (PL XL. fig. 2.) 



T. i-eniformis (Lwrn.), Pocock, Journ. Linn. Soc, Zool. vol. xxiv. 

 p. 404. 



The description already published in the present volume was 

 taken from a large example o£ a Tarantula obtained in the 

 Island of St. Viucent, W. Indies, by Mr. H. H. Smith. 

 . I now offer the following supplement to that description : — 



Granulation of trunk coarse. 



Carapace ilattish, its frontal portion gently sloped downwards 

 and forwards. The distance between the eyes considerably more 

 than half the median length of the carapace and a little more 

 than twice the distance between a lateral eye-cluster and the 

 front or side edge of the carapace ; median tubercle a little wider 

 than long, its long diameter about equal to the distance that 

 sejDarates it from the anterior edge ; this edge distinctly concave, 

 finely dentate mesially, very coarsely dentate laterally, the 

 lateral teeth directed upwards, the frontal process scarcely over- 

 lapped, its apes turned directly forwards and projecting as a 

 distinct spike between the base of the mandibles. 



Mandibles granular above, with two terminal tubercles en- 

 larged, but the external the largest. 



ChelcB coarsely granular above and below. Femur longer by 

 about one-third of its length than the distance between the 

 eyes ; armed almost as in T. harhadensis, but with the spines 

 longer and the first rising from the base of the second, which 

 thus appears double ; the second spine directed more upwards 

 than the third, the first inferior spine as long as the height 

 of the femur. Tibia rather narrow, much narrower than its 

 longest spine ; the spine armature above and below the same as 

 in 2\ barbadensis, as also is it of the tarsus. 



Zeffs long ; femur of the 1st greater by nearly half its length 

 than the width of the carapace, that of the 2nd exceeding the 

 width of the carapace by about one-quarter of its length, equal to 

 the femur of the 3rd and considerably excelling that of the 4th ; 

 tibia of 2nd equal to its femur, that of the 3rd greater by half the 

 patella, that of the 4th greater by the whole of the patella ; the 

 second and third tibials of the 4th two-thirds the length of the 

 fi.rst and longer than the protarsus, the second tibial distinctly 

 longer than half the length of the third and equal to about half 

 the distance between the eyes.
