276 ZOOLOGY. 



between the tentacles, and is surrounded by a double fleshy 

 lip, the outer fold of the lip bearing short fleshy pointed lobes 

 opposite the spaces between the tentacles. The 

 pharynx is large, muscular and bulbous, contain- 

 ing two powerful horny teeth, shaped like a par- 

 rot's beak ; the two jaws are unequal, the lower 

 one the smaller, moving vertically. On opening 

 the base of the smaller jaw, the lingual ribbon or 

 odontophore (Fig. 213, po) may be discovered ; it 

 consists of seven rows of teeth, somewhat as in 

 those of Architeuthis Hartingii (Fig. 215). 



The oesophagus (ce) is long and slender, with two 

 long oval salivary glands (sg) on each side of it, just 

 behind the pharynx; the salivary duct leading 

 into the mouth-cavity. The oesophagus has 

 several internal longitudinal folds, and passes 

 on one side of the large liver (I) which lies in 

 front of the stomach, and which is about one 

 third as long as the whole body, extending back- 

 wards. 



On laying open the stomach, a series of large 

 semicircular transverse curved valves may be 

 Pig. 214. seen, occupying the ^anterior third of_the^stom- 

 Suida, dSi ach (s), while beyond- are scattered glandular 

 ?i d z e -After m asses. ^The pyloric end opens into an oval 

 Verriii. ccecum (ca) with about fourteen longitudinal, 

 thin high ridges. There is no spiral portion attached. The 

 intestine (in) is straight, thick, and passes forward, ending 

 in a large vent (a), the edges of 

 which are lobulated. The " ink- 

 bag" (Fig. 213, t) can be recog- 

 nized as a purse-like silvery sac, 

 filled with a dense pigment, the 

 sepia, which, like the Chinese F'g- 215. Part of lingual ribbon of 



r . , . -, Architeuthis Hartingii ; enlarged. 



sepia, can be used for drawing. 



The duct is straight, and is intimately attached to the in- 

 testine, ending close to the vent, both the vent and open- 

 ing of the duct of the ink-bag being situated at the bot- 

 tom of the funnel or siphon (Fig. 213, /), which is a large
