BULLETIN OF THE UNITED STATES FISH COMMISSION. 
is a genus similar to Cucumaria , but has the pedicels much more numerous and 
crowded irregularly all over the body. 
The members of the Synaptidce may be easily distinguished from all other holo- 
thurians by the absence of pedicels, papillae, and respiratory “trees.” The tentacles 
are pinnate and the body is more or less translucent. Synapta v'wipara is a small 
species, 20 to 100 mm. long, reddish or greenish brown in color with more or fewer 
white spots. It is found living in seaweeds from Bermuda to Brazil. Chiridota 
roUfera is also a small species, rarely 100 mm. long, flesh-colored with little white 
spots, found under stones in the sand. The body-wall contains characteristic wheel- 
shaped bodies. It has been collected from Bermuda, Florida, Jamaica, and Brazil. 
DISTRIBUTION OF SPECIES. 
Of the 50 stations where the Fish Hawk dredged, trawled, or used the tangle, 
86 yielded echinoderms. Their distribution is shown in the following tables and 
statements. The first table treats of the west end of the island, the stations being- 
given as nearly as possible in their geographical order. The Crinoidea and Holo- 
thurioidea are given outside of the tables for typographical convenience. 
Only two representatives of Crinoidea were found in this part of the island: 
Actinometra meridionalis, at station 6063, depth 75 to 76 fathoms; bottom of rocks, sand and 
coral; obtained with 11-foot trawl. 
Antedon hageni, at station 6067, depth 97 to 120 fathoms, coral bottom; obtained with dredge. 
Specimens of the Holothurioidea were found as follows: 
Holothuria mexicana, at Mayaguez, Puerto Real, and Boqueron Bay. 
Holothuria surinamensis, at Puerto Real and Boqueron Bay. 
Stichopus mobii, at Mayaguez and Boqueron Bay. . 
Echinocucumis asperrima, at station 6066, 97 to 120 fms., coral bottom, a dredge being used. 
Asteroidea, Ophiuroidea, and Echinoidea collected by the Fish Hawk at the western end of Porto Rico.
