190 Mr. W. E. Hoyle on the 



area surrounds the horny ring. The hectocotylus is developed 

 in about the middle third of the left ventral arm ; beyond the 

 eighth row of suckers the two ventral series are continued of 

 the normal size, but the two dorsal are each represented by 

 five minute suckers, gradually diminishing to the middle one 

 and then increasing again ; beyond this the arm exhibits 

 no peculiarities. The umbrella is widest between the two 

 lateral arms, where it extends as far as the sixth row of 

 suckers. The buccal membrane bears the usual seven distinct 

 points in the male, whilst in the female the ventral pair are 

 lost in the thick swollen spermatic cushion ; this is subdivided 

 by four or five deep grooves into as many transverse ridges. 

 The outer lijj is thin ; the inner bears about half a dozen rows 

 of distinct hemispheroidal papillaj. 



The Tentacles are about as long as the mantle ; the stem is 

 indistinctly three-sided ; the club is long and wide, and bears 

 eight series of minute equal suckers ; there is a protective 

 membrane on either side and a broad Jin on the dorso- internal 

 aspect. The horny ring is small and has a smooth margin. 



The Surface is smooth. 



The Colour is a dull grey dorsally, pale yellowish below. 



The Shell is broad, subelliptical in outline^ the anterior 

 extremity bounded by two straight lines, which form obtuse 

 rounded-oif angles with each other and the sides of the shell ; 

 the posterior is rounded gradually off". The dorsal surface 

 has a faint ridge passing to each of the three angles just 

 mentioned, and is covered with curved row^s of tubercles 

 parallel to the anterior margin. The ventral surface is but 

 little elevated ; the last loculus occupies one third of it, and is 

 bounded behind by a broadly open curve with three or four 

 irregular sinuations in it. The striated area is hollowed 

 posteriorly and is marked by grooves corresponding to the 

 sinuations just mentioned. The inner cone arises about half- 

 way along the striated area, curves evenly outwards, and then 

 rises into a distinct ridge, forming a wall separate from the 

 margin of the shell ; its ventral surface is marked by a num- 

 ber of striaj pointing in the direction of the spine, which is of 

 medium length and strength, and curved gently upwards.
