between tte tentacles, and is surrounded by a double fleshy 

 lip, the outer fold of the hp bearing short fleshy pointed loLes 

 opposite the spaces between the tentacles. The 

 pharynx is large, muscular and bulbous, contain- 

 ing two powerful horny teeili, 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. 5(jS, p6) may be discovered ; it 

 consists of seveu rows of teeth, -oinewhat as iu 

 those of ArcJiiteufJii" Hartingii (Fig, 210). 



The cesophagus (a?) is long and slender, with twa 

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

 behind the jihanTix ; the sahvary duct leading- 

 into the mouth-cavity. The cesophagns has 

 several internal lungitudinal folds, and jiasses 

 on one side of the large liver (7) which lies in 

 front of the stomach, and which is about one 

 third as long as the whole b."iv, extending lack- 

 wards. 



On laying open the stomach, a series of large 

 ^y semicircular transverse curved valves mav be

 s'fze.-Afrer^^^^^^'-"-- '^^^ pyloric end opens into an oval 

 Vurriu. coecum {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 («), the edges of 

 which are lobulated. The " ink- 

 Lag" (Fig. -208, can be recog- 

 nized as a pui-se-like silvery sac, 

 filled with a dense ijigment, the 

 sepia, which, like the Chinese 

 sepia, can be useil 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. "^08, /), which is a large
