BERMUDA ECHINODERMS. ' L33 



HOLOTHURIOIDEA. SEA-CUCUMBERS. 



1. Cucumaria punctata Ludw. 



Small (two or three inches long), bluish- or yellowish-gray 

 holothurian with ten branching tentacles. Found under rocks 

 along shore. Not very abundant. 



2. Holothuria captiva Ludw. 



Rather small brown holothurian with twenty yellowish shield- 

 shaped tentacles. Ventral surface somewhat flattened, with the 

 numerous feet indistinctly arranged in three longitudinal series. 

 Dorsal surface with rather numerous scattered papillae, situated 

 on small elevations. Not very common but occurs under 

 broken slabs of rock with the following species. 



3. Holothuria surinamensis Ludw. 



Medium-sized holothurian, two to six inches long, of a gen- 

 erally brown color, blotched and spotted more or less indis- 

 tinctly with darker : sometimes tinged with yellow. Tentacles 

 shield-shaped, normally 20 (ranging from 10—21) yellow or 

 whitish. Feet yellowish, not very numerous, scattered, not at 

 all arranged in series. Dorsal papillae not numerous, scattered, 

 rather slender. Found under broken slabs of rock along shore. 

 Quite common. 



4. Stichopus mobii Semp. 



Large holothurian, eight to eleven inches long, buff blotched 

 with black. Tentacles shield-shaped, normally 20 but vary from 

 18-21. Feet arranged in three longitudinal series on the flat 

 ventral surface. Rather uncommon ; on sandy bottoms with 

 the next species. 



5. Stichopus diaboli Heil. 



Large black holothurian, a foot long ; the common holo- 

 thurian of the Bermudas. Except for color, like the preceding 

 with which it occurs though far more abundantly. S. Jiaytiensis 

 Semp. reported from Bermuda by Theel ^ is doubtless this 

 form.
