Family BOLITjENID^ Chun 1911. 
Bolit<Bnid(B Chtin 1911. p. 20. 
Body semigelatinous. Third arms much the longest and largest; suckers on all the arms in a single 
row. Right third arm hectocotylized, tlie chief modification consisting in the enlargement of a part 
or even all of the suckers. Olfactory organ papilliform. 
Genus ELEDOWELLA Verrill 1884 . 
Eledonella Verrill 1884. p. 144. 
EledonellaChmi 1911, p. 16. 
Body gelatinous, weakly pigmented, semitransparent. Hectocotylization affecting only the distal 
suckers of the arm. 
Type. — Eledonella pygmaea Verrill 1884 (monotypic), a species of the New England region. 
Eledonella species (young). 
Bolitcma species Berry 1909, p. 418 (locality record only). 
Mantle saccular, much wrinkled, longer than broad. Arms short, incompletely webbed; the 4 to 6 
large suckers arranged in a single series. Funnel small, little projecting. Plead small. The single 
specimen obtained is too young for safe determination. It is badly contracted and chiefly characterized 
by its large eyes, wide mantle opening extending well past the eyes, and short arms, the third and 
fourth pairs being the longest. The specimen was at first referred to Bolitcena, but is more probably an 
Eledonella.

Animals of small to gigantic size. Body short, thick, and usually firm and muscular. Sexes 
nearly similar. Ventral mantle connection consisting of a pair of shallow folds on the hinder margin 
of the funnel, with shallow grooves to correspond on the inner surface of the mantle. No aquiferous 
pores. Arms with one or two rows of suckers and a more or less well-developed basal web. Hectocotylus 
confined to the extreme tip of either the right or left third arm; a narrow groove or fold in the edge of 
the marginal membrane terminates in a roughly spoon-shaped copulatory organ at the extremity.

Polypus Hoyle 1901, p. 1-5. 
Body short, thick, rounded posteriorly; surface smooth to warty, usually with one or more tuber- 
cular cirri over either eye. Arms and umbrella very variable; suckers in two alternating rows, which 
are perhaps better to be regarded as a single extremely zigzag row. Third right arm hectocotylized. 
Type. — Sepia octopodia Linne 1758, a European species perhaps identical with P. vulgaris (Lamarck 
1799). Schneider designates no type and does not even name a species, but the inference seems clear 
that the Sepia octopodia of Linne is the form which he had in mind, especially since at that time this 
was the only species of the group which had been characterized by a binomial name. Hoyle, however, 
arrives at the conclusion tliat Octopus vulgaris Lamarck 1799 is available as the generic type.
