FRITZMtlLLERI ELON- 

 GATUS. a, FRONTAL 



AND ANTENNAL BEGION. 



^:pecies also occurs in the '' oxyeeros " form (subspecies eIo7if/atHs) , the 



lateral spine of the scaphocerite o^reatly exceeding the carpocerite of 



the antennae, and the rostrum being frequently longer than the lateral 



spines. The subs])ecies eJongatus seems to be almost the only one in 



Venezuela and Brazil. Some specimens received from ]\I. Chaper 



(Venezuela), others received from Fritz Midler from Desterro, and 



a small specimen from Bahia (R. Rathbun, Ilartt Explorations) are 



without excej^tion eJongatus. Aside from their 



longer antennal spine, these specimens have the 



carpocerite less thick (3.3 to 3.4 times longer 



than wide), and the feet of the third pair more 



slender, the meropodite being 3.8 to 4 times 



longer than wide ; but this last character varies 



with the size, and also with the sex, in the 



tj'^pical specimens within a rather wide range. 



With the material at my disposal I can not 



form a conclusion as to the advisability of the 



specific separation of this elongatus form. 



The species is also found in Lower California, 

 from which locality I have been able to study 

 a single male specimen collected by M. Diguet, 

 which does not differ from the Florida speci- 

 mens in regard to the antennae; the feet of the 



third pair are slender, the meropodite being four times as long as 

 wide; but I find the same figures among the small typical males 

 of Florida, of corresponding size, so that I can not separate this 

 specimen from Lower California, even as a distinct " race." 



Named for the naturalist, Dr. Fritz Miiller.
