Fortiinately two excellent colored drawings were made of this specimen 

 when it was captured, which give a much better idea of its general appearance 

 than could be obtained from the sadly mutilated creature which came into 

 my hands. The animals of this family seem particularly difficult to preserve, 

 whether it is that tlieir gelatinous tissues are not easily permeateil by the 

 alcohol or what the cause may be I know not, but no single well-preserved ex- 

 ample of this family has ever come into my hands. ^ In the present instance 

 the body was much decomposed, especially on the dorsal aspect, where the integ- 

 ument and subjacent tissues had entirely disappeared, leaving the cartilage in 

 situ, but with its upper surface clearly exposed to view (Plate 3, Fig. 2) in 

 such a way as to leave no doubt as to what was its normal position. The 

 significance of this in reference to the generic position of the species I have 

 already dwelt upon. 



I have remarked above that the figures and description of the examples 

 called by M. Joubin (: 01) Cirroteuthis unihellata present a very striking 

 resemblance to the species just described. This identification does not rest on 

 a comparison with the type, and seems to me to be at variance with an impor- 

 tant passage in Fischer's ail-too-short diagnosis. Unfortunately M. Joubin 

 gives no account of the form or position of the internal cartilage, which would 

 furnish important evidence for or against the view here suggested.

The Body is ovoid, broadest just in front of the fins, tapering slightly towanls 

 the hinder extremity. The Jim are about e<inal in length to the breadth of

 obtained by the use of a refrigerator.
