The anterior part of the body is cylindrical, posteriorly 

 tapering to a point from the insertion of the fins. These 

 form together a broad transverse rhomboidal outline. Their 

 breadth is more than their length as is seen from the mea- 

 surements above. The lateral angles are a little rounded. 

 The fins are not inserted at the back all along the median 

 line, but have anteriorly each a broad rounded free lobe (22 

 mm. in the larger specimen) by which the anterior portion 

 of the fins gets a heart-shaped form. The posterior angle of 

 the fins is obtusely pointed. The anterior mantle-margin is 

 almost straight with a short, broadly rounded median process 

 on the back. Ventrally it is slightly sinuate and shows a 

 blunt point on each side. 



The pallial surface as well as that of the head has a 

 very peculiar warty appearance. These warts are produced 

 by rather large subcutaneous papillse which make elevations on 

 the otherwise smooth integument, or it may be more correct to 

 say that the skin has sunk down in the interspaces between the 

 papillse forming a network of grooves on the surface, by which 

 the outer aspect becomes rather peculiar and to a certain extent 

 resembles the pavement of an old style street. The papillse 

 themselves seem not to be arranged in any regulär way. 

 This structure is exceedingly interesting not only for itself 

 but also because it helps to throw light on a question in the 

 Teuthology which has hitherto seemed more than .stränge. 1 

 Although these specimens of Onychoteuthis i><f/ens are in a 

 very good state as objects for a museum they are naturally
