 The Body is thick and rounded; the fins are round, nearly circular, and 

 rather more than half the body in length; there is a notch at the anterior but 

 not at the posterior origin from the mantle ; a broad ligament unites the mantle 



with the head in the nuchal region ; the ar- 

 ticulation between the mantle and the siphon 

 consists of an elongated ridge and groove 

 as usual in the family ; the siphon is conical 

 and reaches just to the gap between the ven- 

 tral arms. 



The Head is very broad and the eyes very 

 large and prominent. 



The Arms are in order of length 3, 2, 

 1=4; rather thick, rounded, and tapering, 

 with no trace of keel, or protective mem- 

 brane; the suckers are, speaking generally, 

 in four rows, though the arrangement is here 

 and there a little irregular ; those at the root 

 an<l tip are in two rows, and there appear 

 to be one or two sets of three between ; they 

 are spheroidal, oblitjue, ami of the type usual 

 in Sepiola. In the male the suckers are some- 

 what difftrently disposed ; in the first right 

 arm (Fig. B) the two outer rows of suckers are a little larger than the inner,
