Tarantulidae in the British Museum. 289 



A single male example from New Granada, ticketed, 

 probably by either Gervais or Goudot, Phrynus chiracanthus. 



Subfam. Phbtnicrinm. 



(Simon, he. cit. p. 49.) 



The following three genera of this subfamily are known 

 to me : — 



a. Tibiae of the fourth pair of legs undivided, 



mandibles larger Phrynichus, Karsch. 



Type lunatus (Pall.). 



b. Tibiae of fourth pair of legs bisegmented, 



mandibles smaller. 

 a 1 . Second abdominal sternum furnished 

 with a pair of half-moon-shaped ap- 

 pendages ; larger Titanodamon, g. nov. 



Type Johnstonii, sp. n. 

 b 1 . Second abdominal sternum without ap- 

 pendages ; smaller Nanodamon, g. nov. 



Type anmdatipes (Wood). 



The genus Damon of C. Koch, of which the type is varie- 

 gatus of Perty, also belongs to this group. According to 

 Simon it is congeneric with the West-African forms to which 

 I have given the name Titanodamon. Unfortunately I have 

 had no opportunity of examining either variegatus or any 

 allied species from the same geographical area (*. e. South 

 America) ; and my reasons for proposing the two new generic 

 names given above are : (1) my ignorance as to whether 

 variegatus of Perty possesses the abdominal appendages or 

 not, and (2) my opinion that the South- American forms, if 

 indigenous, possess in all probability some hitherto undis- 

 covered characters by which they may be generically recog- 

 nized from the two African genera. This a priori supposition 

 may of course prove erroneous ; but analogy justifies its con- 

 ception until proof on the matter is forthcoming. 



Genus Titanodamon. 



The British Museum has examples of the three following 

 species : — 



a. Frontal process small, vertical, with its apex acute 

 and turned forwards. 

 a 1 . The posterior of the three long spines on the 

 tibial segment of the chela short, not half the 

 length of the median spine ; the second tibial 

 segment of the fourth leg less than, or, at least, 

 not greater than, the distance between the eyes, tibialis (Sim.).
