CEPHALOPODA. — BERRY. 291 



Arms rather short ; sometimes apparent from above, but 

 usually evident only as stout cartila-ge-like thickenings in the 

 umbrella. Suckers uniserial and very small ; essentially 

 equal in size over almost the entire length of the arm, only 

 the three basalmost and those toward the tip being appre- 

 ciably, though gradually, smaller than the remainder ; 12th- 

 18th possibly largest in the series, but this a point difficult 

 if not impossible to specify : visually well elevated ; in the 

 va.siform stage with umbrella closed the suckers very close 

 together in a given series, more distant in the fully expanded 

 phase, as also in the preceding species ; each series flanked 

 on each side at a distance of perhaps three sucker-diameters 

 by a series of small, retractile, glove-finger-like, pointed cirii 

 corresponding in number to and occurring in apparent alter- 

 nation with the suckers ; the narrow pockets into which the 

 cirri retract very conspicuous in this species (PI. Ixxxii., fig. 

 9), due very likely to the pale color of the contained portion 

 of the cirri as contrasted with the dark pigmentation of the 

 subjacent tissues, in outline straight, extending transversely 

 from the small, crescentic openings about two-thirds the dis- 

 tance to the row of suckers, or sometimes obliquely back- 

 ward, depending upon the position or state of contraction of 

 the surrounding tissues ; suckers themselves likewise more 

 or less retractile, though rarely, so far as seen, to the same 

 degree as in 0. plufo ; total number of suckers to be made 

 out clearlv bv the naked eve on the arms of the right side 

 of type 1-78, 2-78, 3-72, 4-72. Umbrella (Pis. Ixxxvi, Ixxxviii) 

 ample, its greatest extension usually in front, though it 

 extends between all the anus nearly to their extremities, the 

 latter being more attenuate and free of the web for a slightly 

 greater distance than in 0. pluto. A bilateral symmetry in 

 the disposition of the anns and web is to be found here as 

 in plufo, but the peculiar curvatures of the arms noted in 

 the case of the latter species are not so evident in the present 

 series of specimens. 



Colour of specimens preserved in formalin solution ; outer 

 or aboral surfaces of the type and other Victoria specimens 

 practically colorless, or a sort of dirty gray, except for traces 

 of small areolae and of a delicate, much torn, superficial 

 membrane lightly pigmented with streaks of brown ; oral 

 surfaces with the superficial integument colorless and trans- 

 parent, its interbrachial portions very loose, lying in soft folds 

 and wrinkles over the smooth, pigmented layer beneath, the 

 dark bluish slate of the pigmented layer showing through 

 everywhere except that it is paler along the arms and over 

 a ring-like zone a little distance from the mouth ; suckers
