A. E. Verrill — North American Cephalopods. 
guarded by two slender papillae ; of a long, rather wide, tubular por- 
tion, extending back to the base of the caudal fin, and covered, along 
the ventral^side, with lateral rows of clusters of small follicular 
glands, which, near the liver, diverge into two, separate, large, lateral 
clusters ; posteriorly, where the rows of follicles cease, there is a small, 
firm, bean-shaped, glandular organ, lamellose within (? a gizzard) ; this 
is followed by a long tubular, or fusiform, more or less saccular stomach 
and csecal appendage, running back nearly to the end of the body ; a 
constriction at the origin of the ca?cal appendage. The testicle 
is a rather small, slender, lanceolate organ, attached laterally, for its 
whole length, to the side of the ctecal appendage. The prostate 
gland and vesiculre seminales have their usual position, at the base 
of the left gill, but they are small, and probably not fully developed; 
the efferent duct extends over and a short distance beyond the base 
of the gill, and is slender and pointed. The renal organs are very 
different from those of the common squids ( Loligo and Ommastre- 
phes). The posterior part of the anterior vena-cava becomes glandu- 
lar in front of the heart ; there it parts, sending a long, smooth vein 
to the base of each gill; there, each of these veins expands into an 
ovate renal organ, before joining the branchial auricles. 
Family SEPIOLID^E (See p. 367.) 
During the explorations made by the “ Fish Ilawk,” the present 
season, we were fortunate in obtaining additional specimens, includ- 
ing both sexes, of the very interesting and beautiful species described 
by me in 1878, under the name of Sepiola leucoptera. These speci- 
mens have given me an opportunity to make dissections, which I had 
not done with the few r specimens previously known. These studies 
show' that it has no pen ; that the presence of the remai’kably 
enlarged suckers of the second pair of arms is not confined to the 
male ; and that this species is the type of a very distinct genus, espe- 
cially remarkable for being the only known genus, among Myopsulce , 
that has round pupils and the eye-lids free all around. In fact, it 
shows quite conclusively that this division of the Decacera into two 
groups, based on the presence or absence of free eye-lids, is purely 
artificial and of little or no systematic value. Therefore the char- 
acters attributed to the family, Sepiolidce , must be modified to a con- 
siderable extent, to include this genus. 
In its internal anatomy this genus differs but little from Sepiola, 
Heteroteuthis and Eossia, notwithstanding its remarkable divergence 
in respect to the eyes and pen. Other genera of Sepiola-shaped
