Cole (in Sumner, Osburn, and Cole, 1913) suggested two other 
species as possible members of the Woods Hole fauna: Nymphon 
grossipes and Pycnogonum littorale. They are yet to be collected from 
that precise locality. 
THE CARIBBEAN 
Thirty-four species and 16 genera of pycnogonids have been 
identified from the Caribbean region, most of them from the vicinity 
of the Tortugas Marine Laboratory of the Carnegie Institution of 
Washington, and Key West, Fla. Several of them were originally 
described from such widely scattered localities as Norway, Naples, 
Cape Verde, and the Galapagos. 
The characteristic element of this fauna is the genus Anoplodactyius. 
This genus is predominantly tropical and is as characteristic of warm- 
water regions as Achelia is of temperate latitudes and Nymphon is of 
the colder water of the higher latitudes. Anoplodactylus is repre- 
sented in the West Indies by at least 13 species. ‘Two of these, 
Anoplodactylus lentus and A. insignis, appear to be common, but the 
others are represented by one or two specimens or sporadic collections. 
The relatively large size and conspicuous coloration of these two 
species may account for this greater apparent abundance. <Anoplo- 
dactylus lentus often has a spread of nearly 3 inches (7.5 cm.) and is of 
a deep purple color, and A. insignis is well over an inch in extent 
(2.5+ cm.), with prominent angular processes on the joints of the legs. 
The species of Anoplodactylus from the Tortugas region are listed 
in table 2 (A. carvalhoi has been collected from the Virgin Islands but 
is not yet known from Tortugas). 
The occurrence of Anoplodactylus polignaci off Sombrero Key, Fla., 
is of interest in connection with Bouvier’s (1914a) opinion that its
