Uroplectes carinatus (Poc). 



Lepreus carinatus, Pocock, Proc. Zool. Soc, March 1890, pp. 129, 130, 

 pi. xiv. fig. 3. 



Prof. Kraepelin * has recently asserted that this species is 

 identical with planimanus , Karsch ; but the examination of 

 examples of the latter species has shown me that the two, as 

 I originally supposed, are distinct. In carinatus the tail is 

 more strongly keeled, the median keel being quite strong on 

 the third segment and distinctly traceable on the fourth, and 

 the inferior keels on all the caudal segments and the vesicle 

 are distinctly granular. In planimanus the inferior keels are 

 smooth on at least the first and second caudal segments, 

 weakly granular on the rest, vesicle punctured nasally, 

 the median lateral crest absent on the fourth caudal and 

 exceedingly short on the third ; and, lastly, in planimanus^ 

 as the name indicates, the hand, especially in the male, is flat 

 above, broad, and with its inner edge compressed, whereas in 

 carinatus it is thinner and of the normal spherical form. The 

 small disparity in size between the type of carinatus and the 

 smallest male of planimanus lends no support to the suppo- 

 sition that these distinctions are due to differences of age. 



Unfortunately we have no nearer locality for this species 

 than S. Africa, near the Tropic of Capricorn. It agrees with 

 my examples of planimanus in having nine distinct median 

 rows of teeth on the digits, without counting the exceedingly 

 short apical set. According to Karsch there are only eight 

 rows of these teeth. 



Uroplectes variegatus (C. Koch). 

 Tityus variegatus, C. Koch, Die Arachniden, xi. p. 9, fig. 855 (1845). 

 Colour pale yellow, variegated with black; the interocular 

 area black, mesially flavous in front, the area of the carapace 

 behind the tubercle with a black edge, irregularly fuscous 

 laterally and fuscous in the middle. The tergites adorned 

 with seven black lines, the three keels on each and the lateral 

 edges being black, with a large black patch between the edge 

 and the lateral keel ; the tail black-lined, the pigment 

 marking the keels ; there is also a black line in the middle of 

 the dorsal surface and one in front in the middle of the infe- 

 rior surface; the fifth segment fuscous throughout, only 

 obscurely fulvo-lineate ; vesicle entirely pale, aculeus poste- 

 riorly black. Cheliceras entirely pale. Chelas with trochanter,
