Tn size /. l^irtrtl is nearly similar ti) /. Jiotoidcs. I have seen no specimens 

 of it. but the characters of tlie hectdcotyhis as described are such as to lead me to 

 lielicxe the sjiecies unquestionably to lie valid. 



IDIOSEPIUS NOTOIDES sp. nov. 



Chart No. i i and fig. 67. 

 Diof/iiosis. Dodv sm;dl in both sexes. l)ut the male especially so; cylindrical, 

 obtusel}' pointed liehiud and with a distinct \entral flexion. Fins small, semi- 

 circular, about one-third as long as the body, narrowly attached, strongly posterior 

 but not terminal in position. //(■(((/ moderately large, nearly as wide as body. 

 Adiis short, not very dissimilar in length, about one-third as long as body, the 

 second i)air usually a little longer than any of the others. Suckers small, rather 

 crowded, biserial throughout. Roth ventral arms in the male hcctocotyH.rcd ; 

 normal for most of length ami liearing 7-1 i sucker 

 pairs of the usual tyjie : right ventral arm with tlic 

 conical tip simple and free of suckers; left ventral arm 

 appreciabh- longer than right and with a few more 

 suckers, its tip verticallv Iiifurcating into a pair of 

 much compressed, recurved flaps. Tentacles short, 

 stout, one and a half to one and three-quarters as long 

 as the arms. Clubs large, including nearly the whole 

 exposed length of the tentacles; keel wanting, but 

 sucker-bearing area ijordtred liy a delicate memlirane 

 ti]) and base of club but crowded into three or four on middle. Colour of female 

 I'.fter pireservation, light 1)rown, cons])icuously mottled \\'ith patches of slaty 

 clu-omati.ii^hores : the male uniformh slaty with a few minute light spots.

 Remarks. The characters chieflv relied on for the specific discrimination of 

 tin's little squid are tlie suckering of the tentacles nearly to the liase. the large 

 luuuber of suckers on the sessile arms (twice as many as are figured for 

 /. pyymaeus). the extent to which the \eutr;d arms of the male remain normal, 

 and the curious double flap which terminates the left member of this pair. Only 

 /. pieteti seems to attain so large a size, although the males of the present species
