Diagnosis. — Size small; body cylindrical, with bluntly rounded 

 posterior end; introvert rather abruptly narrower, about two-thirds 

 length of trunk; tentacular crown small (Theel, fig. 187) with 27 to 40 

 short, grooved tentacles; skin olive-brown, with fine circular creases 

 and tiny brown papillae, rather more closely placed at end of body and 

 in anal region. Retractors two, rather weak, arising in middle third 

 of body and separated to head; fixing muscles variable, attached to 

 esophagus, to rectum, or to both; spindle muscle not attached poste- 

 riorly, esophagus attached to retractors by well-developed mesenteries; 

 a small rectal coecum; intestinal spire long, with numerous coils; 

 contractile vessel present in north Atlantic forms; nephridia short, 

 opening on level with anus. 



GOLFINGA eremita CALIFORNICA, new subspecies 



The California specimens have no functional contractile vessel 

 except possibly for a very short distance back of the head, whereas 

 both Gerould (1913) and Wesenberg-Lund (1930) state that it is 

 present in North Atlantic specimens. Gerould's figure 1 shows a well- 

 developed vessel. In two of my specimens there is a single fixing 

 muscle on the right side in the position shown in Th^el's figure 173, 

 but it is attached to the rectum behind the coecum. A third specimen 

 lacks this muscle but has a rather long fixing muscle, arising on the 

 left side, attached to the esophagus by two branches. There is a 

 strong spindle muscle (not present in Gerould's specimens), which is 

 attached close behind the anus and fused with all rectum as far as the 

 small coecum. The long intestinal spiral has about 55 single coils. 



The specimens vary Ln length from 15 to 33 mm., and the introvert 

 varies greatly; in one case, measured from anus, it is as long as the
