the text showing that the index is longest in young shells (at 
which period it is natural to expect that growth would be more 
rapid) and becomes shorter with age. 
I have to thank Mr. Robson of the British Museum, and Mr. 
Nichols of the Dublin Museum, for giving me every facility to 
examine eastern Cephalopods in their charge. 
I am indebted to M. Edouard Lamy for taking much trouble 
to find a number of specimens in the Paris Museum, and to my 
colleague Mr. Farran for much help and advice. Mrs. Russell is 
responsible for the illustrations. The three parts of Dr. Hoyle’s 
‘““ Catalogue of Recent Cephalopoda’’! have of course been invalu- 
able, as they must always be to anyone working out a large collec- 
tion of Cephalopoda. All the speciinens except where otherwise 
stated have been preserved in alcohol.

These are all in very bad condition but appear to be of the 
same species, The two last-named and specimen M ‘+ are in 
sufficiently good condition to show that their general contour 
bears a strong resemblance to the photographs of C. grimaldiz, 
Joubin, which is characterized by its egg-shaped body, enormous 
eyes, and small fins set in a line with the posterior end of the 
body. Specimens M 247* and; M 222° are much larger than the 
others and are in Eementaey Seadiae The dorsal cartilages 
of M **°* and M *+* were examined as they were protruding from 
the integument, and resemble fairly well the scheme of Joubin 
(l.c., fig. 7) designed after feeling the cartilage through the skin. 
The dorsal cartilage of the other specimens, felt through the 
skin, seems to be of the same shape. 
It is very like that of C. meangensis, Hoyle (1886, fig. 5) 
except that the outer curves of the ‘‘ horse-shoe’’ are less angular. 
The fin cartilage resembles that of C. grimaldii. All the 
specimens agree with the type in the arrangement of the single 
row of arm suckers. The three or four next the mouth are very 
minute, and are suddenly succeeded by very large ones until
