smaller. The suckers of the sessile arms are deep, very oblique, with 
a high rim, which has on the outer margin a number of regular, 
long, slender teeth, rather close together. 
The whole surface is rather regularly and closely spotted with 
purple chromatophores. 
The eggs are large, 5 T; ^ to in diameter, and comparatively few 
in number. In one female (No. 379) taken in July, the oviduct was 
distended with the eggs, which have a reticulated surface before 
reaching the glandular portion. This female had spermatophores 
attached to and around an elevated area on the inner ventral surface 
of the inner buccal membrane. 
The oviduct is large and its external orifice has a wide ear-shaped 
border, more complicated than in Loligo. The nidamental glands 
correspond nearly with those of Loligo , but are relatively larger. 
In some of the males, taken in July, the sperm at ophore-sac and a 
saccular dilation near the orifice of the efferent duct, were filled with 
spermatophores, much like those of Loligo. 
Hie male has the left ventral arm hectocotylized much as in Loligo. 
The stems of the suckers, for a considerable distance, toward the tip 
of the arm, become long, stout, conical, and many of them, in both 
rows, lack the rudimentary suckers. 
This specie;* is widely distributed along the tropical coasts of 
America, and throughout the West Indies. Martinique (Blainville) ;

The genus Sepiotcuthis is closely related to Loligo in all external 
characters, but its fins extend along nearly the whole length of the 
mantle, and the body is stouter, more ovate, and less pointed behind 
than in Loligo , so that the form is somewhat like that of Sepia. 
The pen is thin and lanceolate, nearly as in Loligo , but in many 
species the blade is thickened toward the margins. The internal 
anatomy is, however, very different from Loligo , iu several respects. 
The ovary is short and thick, and confined more to the posterior por- 
tion of the body. The eggs are comparatively few and very large, 
being 5 mm to 8 ^ in diameter, in our species.
