adult, rather than immature, as would have been the case had they been 

 P. hemphilli. The proposed new species is therefore a small species, 

 whereas P. hemphilli becomes quite large (29 mm or more). Futhermore, 

 the length of the first walking leg in P. hemphilli is fully two and one- 

 half times the length of the carapace, including the rostral horn, while 

 that of the new species is not over two times the carapace length. Lastly, 

 the dactyl of the first walking leg in P. hemphilli is slender and unarmed, 

 and dissimilar to the dactyli of the remaining pairs, while that of P. 

 veleronis is stout and spinulous, and similar to the dactyli of the remain- 

 ing pairs. 



The new species takes its name from the laboratory cruiser Velero 

 III, which during the ten years between 1931 and 1941 contributed 

 materially to our knowledge of the distribution of the genus Podochela 

 in the eastern tropical Pacific.
