IS -MR. E. S. GOODEICH ON A COLLECTION OF 



on to the flaps already described lying opposite them.* I have confirmed these 

 observations on the second specimen. 



Contrary to Verrill's observations in two other species (9), I find on either side 

 between the eye and the funnel a truncated olfactory papilla (fig. 76). It is slightly 

 expanded and flattened distally, the flat oblique surface being concave. 



The head appears to have been narrow. The two eyes are very large and protrude 

 from their sockets. 



The arms are thick, and of considerable length for this genus. The three dorsal pairs 

 are provided on both sides with a well-developed lateral membrane (largest in the third 

 pair), springing from the inner edge and supported by muscular thickenings arising 

 from the base of each sucker (fig. 73). The ventral arms are also provided with such a 

 membrane on the lower edge ; but it is rudimentary on the upper side, where on the 

 contrary the outer edge of the arm is produced into a lateral keel. On all the arms we 

 find two rows of suckers, largest on the third pair. The suckers (figs. 77, 78), very 

 obliquely set on a short stalk, have a wide opening provided with a horny ring, armed on 

 the distal margin only with about 14 squarish teeth. The papillary area is narrow. 



The tentacular arms are thick- stemmed, the clubs only slightly enlarged and bearing 

 a lateral membrane on either side similar to that of the arms. The suckers of the club 

 are compressed and considerably injured in this specimen ; they appear to be set in 

 four rows, and of a peculiar conical shape (fig. 80). The stalk of the sucker sw^ells 

 gradually to the base of the cup, where there is a thickened ridge ; it then narrows and 

 expands again into a bell-shaped cwp, with an oblique opening. The margin of the 

 horny ring is armed with eight or nine strong curved teeth, extending round the distal 

 two-thirds of the circumference. The striated outer margin is frayed out into a fringe, 

 but this is probably artificial. From the club extending down the stem are small short- 

 stalked round suckers, the horny margin of which is armed all rovmd with blunt teeth 

 (fig. 79). Distally at the base of the club these suckers are placed in four rows, which 

 dwindle gradually to two rows proximally, where the suckers are very small and set in 

 pairs on either side of a median groove. 



The buccal membrane has seven ridges ; the lobes are indistinctly marked. 



Purplish-brown chromatophores colour the fragments of skin adhering to the head 

 and arms, the lateral membranes between the ridges, and the buccal membrane. 



The pen can be seen, wdthout dissection, as a narrow ridge starting from the nuchal 

 ]ilate and exjianding posteriorly into a thin plate, narrowing again to form a slender 

 cone, as figured by Pfefi'er for Taonius {Ilegalocranchia) maximns (6). 



The second specimen is very much smaller, and is possibly a young individual of the 

 same species ; it is, however, not in a sufficiently good state of preservation to allow one 

 to make certain of its specific identity. 



* In their normal position the jioints of the flaps are directed away from the middle line ; in figure 74 they 

 iirc directed inwards owing to the stretching open of the funnel.
