single specimens, and it is probable that future dredging in this area 
will turn up other curiosities. 
CALYPSOPYCNON, new genus 
Chelifore 2-jointed, scape trumpet-shaped, the chela chelate and 
hidden within the rim. Palpi 9-jointed. Oviger 9 (or 8?)-jointed, 
without a terminal claw. Propodus and terminal claw long, tapering. 
Body elongate, segmented. The structure of the chelifore resembles 
that of Nymphopsis, but the very long terminal claw of the leg, 
together with the short tarsus, resembles Nymphonella Ohshima 
(1927). 
The pycnogonid described below was found among the collections 
of A. E. Verrill by Dr. Stanley C. Ball at the Peabody Museum.
