194 Mr. W. E. Hoyle on the 



globular, slightly oblique, with a small aperture and smooth 

 horny ring. The hectocotylus occupies the distal half of the 

 left ventral arm ; the suckers are normal up to the twelfth 

 rowj after which the arm widens and has a median groove 

 from which about twelve shallow grooves pass outwards on 

 either side, separating raised portions, each of which bears a 

 minute sucker on the dorsal side of the groove. The umbrella 

 is present only between the second and third and third and 

 fourth arms up to the fourth row of suckers. The huccal 

 membrane is well developed and has the usual seven points ; 

 in the female there is a thick deeply grooved spermatic 

 cushion. The outer Up is thin and smooth, the inner thick 

 and papillate. 



The Tentacles are somewhat longer than the head and 

 body, very slender and somewhat flattened. The club is 

 flattened and expanded ; along its outer margin is a very 

 narrow membrane, and along the median edge, at some dis- 

 tance from the cupules, is a broad web, marked on the dorsal 

 aspect with fine parallel shallow oblique grooves ; along one 

 margin it bears three or four series of small pedunculated 

 suckersj whose horny rings bear very numerous and acute 

 teeth. 



The Surface is smooth. 



The Colour is a dull purplish grey above, ochre with purple 

 chromatophores below. 



The Shell has a narrow elongated oval outline, somewhat 

 pointed in front and tapering gradually backwards ; the chiti- 

 nous margin extends about one third across the dorsal surface, 

 which shows the boundary lines of the loculi clearly as brown 

 strise, and is very minutely roughened : the ventral surface 

 is elevated, so that the shell is thick in proportion to its 

 breadth, a narrow groove runs down the centre : the last 

 loculus occupies one fourth of the surface and is bounded poste- 

 riorly by a shallow open curve. The posterior extremity is a 

 very flattened irregular cone, to the apex of which the spine 

 is attached ; the in7ier cone is very shallow and its opening 

 is some 4 millim. from the margin of the outer cone. The 

 spine is long, straight, and points directly backward.

The Body is narrow, widest anteriorly, and tapering gradu- 

 ally backwards : the^n is narrow, less than one quarter the 

 breadth of the body, widening a little behind ; it commences
