286 Mr. R. I. Pocock on the Pedipalpi of the Family 



fourth leg equal to about one third of the distance between 

 the eyes. 



Measurements in millimetres of type. — Total length 11*5 ; 

 carapace, median length 7, width 11*5, distance between eyes 

 4'5. Chela : length of femur 5, tibia 7*5, tarsus 3*7, digit 

 4*3. Legs: femur of first 16, of second 12*5, of third 13*3, 

 of fourth 10-5. ^ 



Loc. Colombia (Magdaleine). Goudot Coll. Type. Also 

 specimens of apparently the same species from Venezuela, 

 Trinidad, and British Guiana. 



Genus Phrynopsis, no v. 



The two known species of this genus may be recognized as 

 follows : — 



a. The spine between the two longer ones on the upper 



edge of the tibia of chela as long as the third spine 

 from the distal end of this segment ; the spines 

 forming the proximal half of this series smaller, 

 the spinules larger coronatus (Butl.). 



b. The spine between the two longest on the upper 



edge of the tibia minute, much smaller than the 

 third from the distal end ; the spines forming the 

 proximal half of this series larger, the spinules 

 smaller spinifrons, sp. n. 



I have seen one example of each of these species. That of 

 coronatus, contained in the late Count Keyserling's collection, 

 is dried and much mutilated and has no locality assigned to 

 it. It agrees, however, so far as I can judge, with 

 Mr. Butler's figure and description of the type, which is in 

 the hands of the Rev. 0. P. Cambridge. The example of 

 spinifrons from Ciudad, in Mexico, will be figured and more 

 thoroughly described in a future publication. 



Genus Heterophrynus, Pocock. 

 Heterophrynus, Pocock, Journ. Linn. Soc, Zool. xxiy. p. 527 (in note). 



This genus contains H. pumilio, C. Koch (Die Arachn. 

 viii. p. 15), from Brazil, and H. gorgo, of Wood (Tr. Am. 

 Phil. Soc. xiii. p. 440), from Peru. 



"We have neither of these species, to my knowledge, in the 

 British Museum. H. pumilio, however, will very probably 

 prove to be the young of one of the four enumerated below. 



The species that I have succeeded in identifying are : —
