specimens are faded and colorless except for a wedge-shaped brown 

 or purple spot in front of the lateral tentacles, a rich madder purple 

 coloration of the notocirri and a brown spot at the end of each anal 

 cirrus; others show traces of a more extensive purple coloration, 

 especially on posterior segments. The under parts, including the 

 neurocirri, are always colorless, as are the tentacles and one to three 

 or four pairs of the anterior notocirri. Not infrequently also, the 

 color is lost more or less completely from the styles of IV, V and VI, 

 but the cirrophores always retain the deep purple color. A specimen 

 from station 4,416 is of a fine rosy color above with a median series 

 of white oval spots. Several specimens from station 4,454 have the 

 notocirri brown and the ventral surface, proboscis and rarely portions 

 of the dorsal surface spotted with sharply defined, quadrate, brown 

 spots. Sometimes only three or four occur on the entire ventral 

 surface, in which case some are likely to occur on the dorsum; some- 

 times they are much more numerous and in places crowded or even 

 coalesced and rarely the spots are X-shaped. 



Chlocia pinnata is one of the most abundantly represented and 

 generally distributed species included in this collection. There are 

 in all nearly three hundred specimens, about half of which came from 

 stations 4,460, 4,475 and 4,552 and about twenty each from stations 

 4,349, 4,480 and 4,485, all of these being muddy bottoms. No less 

 than ninety-seven were taken at station 4,475, from among which the 

 type was selected.
