NO. 9 HILTON: PYCNOGONIDS 311 



Ovigers: Slender, the joints not very different in length. The 5th 

 and 7th joints seem the longest. 



Ambulatory appendages : Rather short and heavy. The 1st joint is 

 about like the 3rd coxal joint. The femur and tibiae are not very long, 

 the first two longer than the 2nd tibia. The 1st tarsus is rather short ; the 

 2nd is nearly as long as some of the long leg joints. All the joints except 

 the last two are reticulated, marked by dark brown lines. 



The claws are about half as long as the last tarsal joints. 



Color: Brown. Reticulated. 



This species is nearest to Pycnogonum hancocki Schmitt, found in 

 many places about the Galapagos Islands, but differs in having the pro- 

 boscis longer than the body. It is also of different shape, being narrowed 

 toward the tip in this species and bent downward. The reticulations 

 differ in the 2 species, and the claws are long in this species.
