The side mouth-shields are long, slender, rectangular, not quite meet- 

 ing in the middle and reaching to the border of the genital slit out- 

 wardly. The genital slits are long, reaching to the outer margin and 

 paved on the interbrachial sidewall with large flat scales and mar- 

 gined with tooth-like papillae, similar to but smaller than those of 

 the arm-comb. The mouth papillae are 9 to 10, flattish, blunt, well 

 separated, the apical tooth pointed. The teeth are in series of 9 or 10, 

 one above the other, the innermost one smaller than the others. 



The under arm-plates are broad triangles, well separated from each 

 other in the median line by the meeting side arm-plates. On the 

 distal part of the arm these latter become larger and the under arm- 

 plate smaller, so that the length in the median line is greater than 

 that of the under arm-plate. The side arm-plates are arched, not 

 extending high upon the dorsal surface. There are three stout, coni- 

 cal arm-spines in each series, these increasing slightly in length from 

 ventral to dorsal. The dorsal arm-plates are very wide and short 

 and strongly arched. The proximal pore pair has three or four ten- 

 tacle scales at the inner edge ; farther out there are only two tentacle 

 scales and still farther toward the extremity, only one.

Type: Lamarck designated the habitat of this species as "the seas 

 of Europe and the Atlantic Ocean," and deposited his type in his 

 cabinet; since placed in the Paris Museum. 



Distribution: Known from the coasts of Norway, Denmark, the 

 British Isles, northern France, the Hispanic Peninsula and the Medi- 

 terranean Sea. It has been recorded repeatedly from the tidal zone 

 to 200 meters deep in northern waters and in the Mediterranean from 

 depths reaching to 300 meters. 



Material examined: One large specimen, dredged in 35 fms., 

 N. E. by N. of Cape Carthage, Gulf of Tunis, Mediterranean Sea,
