20 BULLETIN OF THE 
Synapta, sp. (?). 
From the defective state, a close examination is impossible. The handle 
of the symmetric anchors is dentate and the flukes serrated. The anchor- 
plates are rather large, rounded or oval, perforated with numerous holes, and 
at the slightly narrower truncate end, where the anchors are attached, resem- 
ble an irregular network. The margin of the plates is uneven from the pres- 
ence of processes or spines, and spines are also present on the surface of the 
plates at the margin of the holes. Possibly the species is identical with 
Synapta abyssicola, Théel. 
Habitat. Lat. 39° 25’ 30” N., Lon. 70° 58’ 40” W., depth 1394 fathoms ; 
one incomplete specimen. 
Chirodota rotifera Pourratis. 
The largest specimen, which measures about 75 mm. in length, has fifteen 
digits in each of the twelve tentacles (Ludwig only counted twelve digits). 
The wheel papille are principally placed on the interambulacra, but a few 
also occur on the ambulacra, and they are less numerous on the ventral sur- 
face than on the three dorsal interambulacra. 
Habitat. Porto Seguro (Thayer Exp.); several specimens. 
Chirodota contorta Lupwice. 
Habitat. Port Gallant, Patagonia; numerous specimens.
