AETHEOPOD FATTXA Or THE WEST INDIES. 527 



III. Supplement 07i the Pedipalpi of the West Indies. 



On page 404 of the present volume I fell into tlie error of 

 regarding the West-Indian specimens of the genus Tarantula 

 {=■ Phrynus of authors) as belonging to but one species. During 

 the past month, however, a more detailed study of the rich 

 material of this group contained in the collection of the Britisb 

 Museum has shown me that this is very far from being the case. 



As a result of this study, I venture to propose the following 

 new species of the genus. At the same time I deeply regret that 

 I have, with one exception, failed in my attempt to identify any of 

 the species established by previous authors. It is therefore highly 

 probable that I have unknowingly renamed some or all of them. 



In the paper above referred to I have giveu my reasons for con- 

 sidering that the genus in question should bear the name 

 Tarantula. Eor the type of the genus Tarantula of Pabr. is a 

 species named reniformis by Linnaeus ; Linnaeus having based his 

 species upon the figure, published in Brown's 'History of 

 Jamaica,' of one of the members of this group which was reported 

 from the Island of Antigua. jS"ow this figure incontestably 

 represents an animal congeneric with all the species described 

 below, and with only remote affinities with the S.- American Pedi- 

 palp to which Mous. Simon proposed to restrict the term Tarantula *. 



The following synoptical table will, it is hoped, help in the 

 rapid identification of the species here described. It must not 

 be supposed, however, that the species enumerated necessarily 

 differ solely in the characters mentioned. 



Synopsis of the West-Indian Species o/" Tarantula. 



a. Tibia of the chela armed above with 9 spines, of which 



the 3rd from the proximal end and the 4th from the 

 distal end are the longest, there being two spines 

 between these long ones viridieeps. 



b. Tibia of the chela armed with 8 spines, of which the 3rd 



from the proximal and 4th from the distal end are the 



longest, with only one spine between these long ones. 



a^. Tibia of chelae slender, the longest spine longer than 



the width of the segment t ; lateral eye-groups 



mostly closer together, the distance between them 



* This Pedipalp is consequently without a name. I therefore propose that 

 it be called Heterophryims, with chiracanthus of Gervais as the type, 



t The width in this and all cases is taken from the upper inner edge to the 

 under outer edge.
