and fourth pairs of sessile arms; ta, tentacular arms; d', external orifice of si- 
phon ; o v, o v ovary, mostly concealed by the oviduct ; v o, commencement of 
glandular portion of oviduct; a/, large gland surrounding the oviduct; o d', ante- 
rior portion of oviduct; op, orifice of oviduct; xx, pair of large, ventral, lami- 
nated, nidamental glands ; x, pair of folliculated and mottled accessory nida- 
mental glands ; u, one of the urethral openings of the peritoneal membrane. 
Figure 2 . — Loligo Pealei. Embryo taken from the egg, ventral view, much enlarged ; 
a, a, a, ventral arms, tentacular arms, and third pairs of sessile arms; c, c, eyes 
on stout peduncles or lobes from the sides of the head; m, mantle-edge; h , 
branchial auricles ; y, unabsorbed yolk-mass. 
Figure 3. — The same. An embryo, within the egg, somewhat more advanced than 
fig. 2, side view, less enlarged. The lettering is as in fig. 2, with the following 
additions: a', second pair of arms; a ", third pair; a”', tentacular arms; a'"', 
ventral arms ; s, orifice of siphon ; o, otolith ; f rudimentary caudal fins. Chro- 
ma tophores are developed on the mantle. 
Figure 4. — The same. An embryo at the period of hatching. Ventral view, en- 
larged about 25 diameters. The yolk-sac is nearly absorbed. 
Figure 5. — The same. A somewhat older larva, taken swimming at the surface. Dor- 
sal view, enlarged about 7 diameters. The dorsal arms are stiil very small ; the 
tentacular arms are the large-t; the chromatopliores are large and symmetrically 
arranged, but only part of them are figured ; the caudal fius do not reach the 
posterior end. 
Figures 2 and 3 are from camera-lucida drawings of living specimens by the author; 
4 is by J. H. Blake from life ; 1 and 5 are by J. H. Emerton, from alcoholic speci- 
mens.
