Stanford University collections [S. S. B. No. 360], was obtained at 

 Tokio by Jordan and Snyder. It much resembles the preceding- 

 species, but seems clearly referable to S. esculenta since it "lacks the 

 suckers on the buccal membrane and also the callosity of the inner 

 cone. " Despite these differences, the two forms are very nearly allied. 

 Distribution. — Tokio (Ortmann, !); Yokohama Market (type 

 locality, Hoyle); Nagasaki, Hizen (Appellof). Queensland, Australia 

 (Hedley).

Wiilker has . suggested that this species may be identical with 

 S. elliptica and infers that Ortmann may have been mistaken in the 

 most important diagnostic character — the presence of teeth on the 

 horny rings of the sessile arm suckers. I can, however, confirm 

 Ortmann's observation. Suckers of a specimen from Nagasaki 

 show about 35 small, short, broadly conical teeth, their tips squarish 

 (or broken ?), developed with fair evenness all around. In all other 

 respects also this material agrees well with the description of S. 

 hoylei, but indicates that this form is at best so weakly differentiated 

 from S. elliptica that the conclusion attained by Wiilker may yet 

 prove to be correct. 



A specimen before me from Wakanoura is young and too poorly 

 preserved for certain identification, but the gladius agrees well with 

 the Nagasaki specimens.
