45 mm. of the type) and differed from the first procured in 
certain respects which may quite well be due to their being 
adult or older form of the above-named species. The head 
and eye are relatively smaller in the large forms, while the fin 
formula is apparently different, being D. VII 18. A. 13. P. 21. 
V1 3. 
In these fishes, however, the fin formula can only be accu- 
rately ascertained by dissection and in the case of small forms 
it is difficult to ensure that some of the spines or rays are not 
overlooked. 
In the larger forms villiform teeth are apparent in the jaws, 
but none on the vomer or palatine. 
The distance of the ventrals from the snout is nearer + than 
+ of the length of the body.

Fam. CYTTIDAE. 
Cyttosoma boops, Gilchr. 
A smaller specimen than the type, obtained Cape Point 
Lighthouse bearing N.E. } E., distant 29 miles, by shrimp 
trawl on the 11th June, 1903, depth 470 fathoms, undoubtedly 
belongs to the above-named species and throws some interest- 
ing light on the identification of the adult form. In describing 
this species (Mar. In. Vol. III., p.7) the presence of one or two 
large scales was noted without particular importance being 
attached to them. Only one was distinctly seen and is repre- 
sented in the figure (vide Plate NXIII., Vol. IIT.) 
In this smaller form there are distinctly two below the an- 
terior part of the dorsal fin and, in addition, others of a similar 
character along the side and below the abdominal region, and 
there are arranged in a manner closely approximating to that 
shown in Cuvier and Valencienne’s figure of Oreosoma 
atlanticum.
