10 ME. E. S. GOODEICH ON A COLLECTION OF 



12 suckers can be counted. These suckers are very obliquely set on short stalks 

 (figs. 42 & 43), and of a compressed conical shape. The horny ring is studded with 

 tectli, and the margin is armed with small teeth on the proximal side and large blunt 

 teeth on the distal side. 



The tentacular arms are scarcely at all enlarged to form the clubs (figs. 38 & 40). 

 Each club bears a small keel externally, three hooks along the lower edge of the internal 

 surface {Ji), and above these two rows of suckers. Beyond the hooks on the distal region 

 small suckers are arranged in four rows. The horny ring of the suckers is furnished 

 with small teeth round its margin (figs. 44, 45). Near the base of the club a set of 

 three small short-stalked suckers alternating with three tubercles forms a connective 

 apparatus {c. app. fig. 40). 



^i§. 41 (a & b) shows the pen of a small male, the mantle of which is 3 cm. long ; it 

 is lanceolate, with a strong median ridge. This specimen has a large bundle of sperma- 

 toj^hores in the mantle-cavity. 



In colour the female is of j)ale yellowish-brown tinge, inclining to orange on the upper 

 surface, covered with dark purjile-brown chromatophores, most numerous on the upper 

 surface of the mantle, head, and arms, and on the buccal membrane. The male is paler, 

 the chromatophores being less numerous. 



Both sexes are provided with a very large number of small dark tubercles, generally 

 showing a white opaque lens in the centre, distributed over the lower surface of the 

 mantle, head, funnel, and ventral arms (tig. 38). 



These tubercles, no doubt luminous or phosphorescent organs, are evenly scattered 

 over the lower surface of the mantle ; on the siphon they are situated in six irregular 

 longitudinal series ; on the head there is a row round the lower half of each eye and 

 nine rows between these. Three rows extend on to the base of the ventral arms, but 

 only two are continued to their extremities.
