at this part the lower jaw seems a little the longest ; both are 

 armed with several rows of sharp teeth ; the tongue is small. 

 The head is joined to the body by something wliich resembles a 

 neck ; the body is flat so far back as the ventral fins, beyond 

 these it is rounS ; the pectoral and ventral fins are very large ; 

 the former are flat, and both have near their extremities a num- 

 ber of spines. The two dorsal fins are placed far behind ; the 

 lobes of the tail are equal and lunated. There are five spiracula ; 

 the eyes are very small, and the nictitating membrane, which is 

 of the colour of the common skin, contracts over the eye, leav- 

 ing a linear pupil. The body is shghtly rough, of a sandy- 

 brown colour ; the under parts white. It is about five feet long, 

 and keeps near the bottom."

" There are in the possession of William Rashleigh, Esq. of 

 Menabilly, a drawing and memorandum of a fish of this genus, 

 which I am not able to refer to any known species ; it was 

 twenty-nine feet four inches long, twenty-four feet round, the 

 fork of the tail seven feet, and the weight four tons ; in the 

 drawing, the eye is in front, under a snout that projects and is 

 turned upward ; the mouth is two feet and a half wide. The 

 head is deep ; the first dorsal fin much elevated. This fish 

 seems to resemble the basking shark, but differs from it in the 

 form of the head and situation of the eye."

Intending, as before mentioned, to give Mr. Mac Leay's

VI. Some Account of a new Species of Eulophus Geoffroy, By 

 the Same. 



" Eulophus Damicornis, Aureo-viridis : abdomine nigricanti, 

 basi macula paUida sub-pellucida. Long. corp. lin 1|.. Habitat 

 in larva Bomhycis camelina ? Mus. nostr." 



*' This species," Mr. Kirby observes, " is very similar to 

 E. ramicornis (of which, as well as of C. pectinicorniSf I possess 

 British specimens), the principal distinction being the white 

 spot in the base of the abdomen." B.
