Tityus Kraepelini, sp. n. 



Allied to T. magnimanus, Poc, but with the inferior median 

 keels of the third caudal segment not united, merely con- 

 verging in the posterior third of the segment, those of the 

 fourth confluent in the posterior half of tiie segment, without, 

 however, forming a definite median longitudinal crest as in 

 7', magnimanus, but a series of irregularly disposed granules.

 reddish. 



Tail a little longer than that of T. magnimanus ; chelse

 shorter, the movable only as long as the fourth caudal segment, 

 whereas in T. magnimanus it is longer than the fifth (9"5 : 86). 

 ? . — Differing from those of T. magnimanus and trinitatis 

 by the structure of the inferior keels on the third and fourth 

 caudal segments : further difl^ering from T. trinitatis in the 

 greater thickness of its tail (c/. measurements).
