The third family, the Tarantulidae, has a far wider distribution 

 than either of the preceding two. It spreads over the whole of Africa 

 south of the Sahara, from Senegambia and Abyssinia to Cape Colony, 

 along the south of Arabia from Aden to Muscat, from Bombay south- 

 wards into Ceylon and turns up again in Siam, but, so far as is 

 known, does not overlap the range of the Charontidae. Oddly enough, 

 however, the group seems to be represented in South America, ac- 

 cording to the independent testimony of two authors. Three genera 

 are recognisable, namely Titanodamon, with two or three species, 

 ranging from Senegambia to the Congo in West Africa : Tarantula,

with about four species, is spread over Eastern Africa from the 

 Mozambique to Abyssinia, in South Arabia, India, Ceylon, and Siam ; 

 Damon (Nanodamon), with two, perhaps more, species occurring through- 

 out East Africa from Cape Colony to Somaliland and South Arabia ; 

 in South America, one species has been recorded by Perty from Brazil, 

 another by Simon from Patagonia, a little farther south than the 50th 

 parallel of South latitude, that is to say in about the same latitude 

 as the Falkland Islands. 



Erom these data it appears evident that three geographical regions 

 must be admitted for the Tailless Pedipalps. First the Neotropical, 

 characterised by the Admetidae and one genus of the Tarantulidae, 

 which, however, also occurs in East Africa. This region comprises part 

 at all events of Lower California, of Texas, and probably Florida, the
