78 FAUNA OF BALUCHISTAN. 



above specimen somewhat in its sutural line, but it differs from it in the following 

 characters : the first lateral saddle is of the same height as the second lateral (in B. 

 hinodosus the second lateral is higher), and the first lateral lobe is narrow and of 

 the same depth as the second lateral (in B. binodosus the second lateral is much 

 shorter but broader than the first lateral). 



"With regard to this character, B.faujasi, Lam., is perhaps the most closely re- 

 lated form to the'iBaluchistan specimen ; in fact, the features of both species are 

 nearly the same. B.faujasi differs apparently by a more delicate sutural line,^ but 

 chiefly by its more regularly elliptical cross section and the absence of nodules 

 along the aitisiphonal side. It is the latter feature, together with the sutural line, 

 which readily distinguishes B. hinodosus.

Ranina griesbachi, spec. nov. PI. XXII, fig. 4, 



Only one specimen of this interesting species has come under examination, and 

 this is in such a mutilated state that only the anterior part of the carapace is pre- 

 served. This specimen exhibits the following characters. 



The greatest breadth of the anterior part, measured between the second lateral 

 spines, is 58 mm. The front margin, taken as a wbole fropi the base of the rostrum 

 to the first lateral spine, is almost straight. The narrow rostrupa, which is unfor^? 

 tunately a little damaged, must have been short, apparently three-rpointed, and 

 hollowed by a deep but short longitudinal furrow. 



The orbital margin is indented, at about the middle, by two strong incisions, 

 converging in the posterior direction, the outer one of which is slightly longer but 



^ It must be remarked that there are some discrepancies hetween the sutural line of Binkhorst's fig. la and li • 

 in the former external and lateral saddle are of the same height, while in the latter the lateral saddle is distinctly higher 

 than the external one. In fig. la the first lateral lobe is distinctly deeper than the second one, while they !|.re of the 

 same depth in fig. li.
