224 Mr. R. I. Pocock on 
three spines and the protarsi internally with two spines and 
externally with four, the tibie being almost unarmed. ‘The 
claws of these legs are armed with one large tooth and one 
or two smaller ones. ‘lhe sternum offers the usual small 
marginal impressions opposite the coxve of the first and second 
legs, and, in addition, near the middle of its length a pair of 
large somewhat bean-shaped scars, which are close together 
but some distance from the lateral margin. 
Cteniza antipodum and C. hevops, White (P. Z. 8. 1849, 
p. 5), are synonymous, the latter being nothing but a younger 
specimen of the former. The species belongs to the geuus 
Macrothele, and is, perhaps, identical with JZ, Huttoni of 
Cambridge, which is unknown to me. In an evil moment 
Ausserer proposed the genus Hexops for White’s second 
species, trusting the author’s statement respecting the 
number of the creature’s eyes. The statement, however, is 
erroneous, the normal number of eyes being clearly visible. 
Of course Ausserer had no right to change the specific name 
into Whited when choosing to take for his fancied new genus 
the specific name that White proposed; but unfortunately 
Hexops antedates Macrothele, and some authors will perhaps 
boldly say that, notwithstanding its inappropriateness, it 
must consequently supersede it. 
Trechona zebrata (Walck.).—A specimen in the British 
Museum of this species, bearing Walckenaer’s ticket, has the 
inferior claw on the feet strongly developed. It is thus not 
congeneric with the species described by Ausserer as Trechona 
venosa (Latr.) ; and since zebrata is the type of the genus 
Trechona, it is not characteristic of the latter to lack the 
lower claw, as Ausserer states. In fact the genus will 
probably prove synonymous with Hudiplura, Sim. 
Ischnothele caudata, Auss. (op. cit. p. 163), from Yucatan, 
is nearly allied to Mygale guianensis, Walck. The two 
species are undoubtedly congeneric, Simon refers Walck- 
enaer’s species to T'helechoris of Karsch, which is based upon 
a Mascarene species, but whether rightly or not I cannot say. 
Upon & priori grounds I should be inclined to think wrongly ; 
but if rightly, the genus must stand as Ischnothele. 
Thalerommata gracile, id. (op. ett. p. 182), is, as Mons. 
Simon declares, very difficult to classify. The absence of the 
lower claw and the presence of long and thick ungual tufts of 
hairs on the feet refer it either to Simon’s Barychelinee or
