Figure 22 A-B, Sepia sulcata Hoyle; A, male reproductive tract (testis not shown), MV F56919, 65.9 mm ML, scale bar 
1 mm, abbreviations as in Figure 6A; B, spermatophore, MV F56919, 67.6 mm ML, scale bar 1 mm; C, 
female reproductive tract, MV F56918, 90.6 mm ML, scale bar 5 mm, abbreviations as in Figure 6C. 
Spermatophores: cement body clearly bipartite; 
aboral end elongate, cylindrical, connects to sperm 
reservoir via narrow duct which extends from 
nipple-like tip of cement body, connects to oral end 
by narrow neck (Figures 22B, 23); oral end shorter 
than aboral end of cement body, cylindrical, tapers 
evenly to terminal dilation; middle tunic 
commences along aboral part of cement body; 
ejaculatory apparatus coiled, extends into oral 
dilation of spermatophore. Spermatophores 4.8- 
6.0-8.5 mm long (SD, 1.5 mm), 0.25- 0.30 -0.50 mm 
wide (SD, 0.10); SpLI 8.4-10.6-12.6 (SD, 1.5), SpWI 
3.18-5.28-9.43 (SD, 1.86). 
Female reproductive tract: ovary hangs from 
dorsal wall of posterior viscero-pericardial coelom. 
Oviduct thin-walled, continuous with body cavity; 
distally with thickened, glandular walls (oviducal 
glands). Nidamental glands, in mature animals, 
occupy large portion of ventral side of mantle 
cavity. Accessory nidamental glands anterior to 
nidamental glands (Figure 22C). Eggs spherical, 
3.5-4.0-4.4 mm diameter (SD, 0.5); EgDI 4.0-43- 
4.6 (SD, 0.3). 
Dorsal mantle with thick, cartilaginous sub- 
dermal layer; cartilaginous layer adheres closely to 
cuttlebone. Cuttlebone length approximately equal 
to mantle length; CbL males 47- 55.9 -65.6 (SD, 7.8), 
females 60.5 -68.1 -86.5 (SD, 9.7); outline oblong 
(Figure 24A,B); CbWI males 29.4-32.2-34.1 (SD, 
1.7), females 28.7- 31.9 -33.7 (SD, 1.8); acuminate.
