with a greater or lesser development of spines on the dorsal surface 
d^ Pj to P^ distinctly swollen in the first five or six segments, noticeably 
more slender beyond ; basal segments with their distal angles but 
slightly truncated, so that their distal border is relatively long and 
straight, parallel to the longitudinal axis of the pinnule; spines on the 
ossicles of the I Br series and first two brachials never very numerous 
nor long (west coast of Tierra del Fuego and south- 
western Chile and the adjacent islands, from Navarin 
Island northward to Tom Bay, Patagonia; 22 — 326 
Metres) 
d- proximal pinnules not swollen basally, Pj and P„ being extremely 
slender throughout their entire length, their basal segments usually 
with the distal angles deeply truncated so that the dorsal border is 
narrowed to a slightly rounded point which as a rule is crowned 
with a few spinelets ; sometimes these segments have a very spinous 
carinate process

Horn. PI. 12, fig. 2, shows a pinnule almost of the pcrplixa type.
