PISCES. 145 
Pscnes fiiscus, sp. n., Giiiclienot; M(5m. So3. Sc. nat. Cherbourg, 18GG, p. 138, 
Madagascar. 
Naucrates. Dr. Liitken has arrived at the same conclusion witli regard to 
Nauclcriis as Mr. Gill, viz. that it is merely the young state of Nauemtes. 
He also thinks that there is but one species. Vid. Medd. ntrh. Foren. 
Kjobenh. (1865) 1866, pp. 205-208. Dr. GUnther, on reconsideration, lia^s 
removed this genus from the Scomhridee to the Carangidee, Fish. Zanz, 
p. 63. 
CoRYPH^ENIDiE. 
Corgphcena. On the Cuban species described by Cuv. & Val. see Poey, 1. c. 
pp. 331-332. 
\ Ausonia cuvieri. Mr. Couch reports on the occurrence of this rare fish on 
the coast of Cornwall, as having been found for the first time on the British 
coast. He describes the specimen in Proc. Zool. Soc. 1866, pp. 332-335. 
It need scarcely be mentioned that the, in the opinion of the author, impor- 
tant differences between this and a Madeiran specimen do not point to a dif- 
ference of species. — Dr. Gunther has appended notes on the skeleton, ibid, 
pp. 336-338, and figured it *. 
Singularly enough, a second example was captured near Falmouth on 
September 30. Bullmore & Couch, Ann. & Mag. Nat. Hist. 1866, xviii. 
pp. 424 & 425 ; the Cornish Zoologist, 1866, pp. 601-504. 
[The Recorder has seen a sketch of this example, which evidently was the 
male fish, having the anterior dorsal ray prolonged. He has learned that a 
gentleman without ichthyological experience has described it as a distinct 
species in a weekly newspaper I] ' 
Stromateus. M. Guiclienot describes as a new species from Cayenne 
^ Bhomhus orhicularis, M^m. Soc. Sc. nat. Cherbourg, 1866, pp. 243-247. This 
would be a very extraordinary species, if the number of fin-rays (D. ^ , 
A. — ) be correctly stated. 
ScOMBRIDiE. 
4 Scomler pnemnatophorus (?). Dr. Gilpin gives a detailed account of the 
characters and history of the Nova Scotia Mackerel. Proc. & Trans. Nov. 
Scot. Inst. Nat. Sc. 1866, pp. 11-17, 
Scomher scomber. Dr. R. Dyce, in describing the eyeball of the Mackerel, 
direqts attention to a slit in the cartilaginous substance of the sclerotica, 
dividing it into two equal portions. There is a notch in one of the edges 
of the slit for the reception of the optic nerve. Ann. & Mag. Nat. Hist. xvii. 
pp. 307-309, with a plate. 
Thynnus. On the Cuban species described by Cuv. & Val. see Poey, 
Report, fis. -nat. Cuba, i. pp. 320-322. 
Cyhium. On the Cuban species described by Cuv. & Val. see Poey, 1. c, 
p. 322. 
Behemis, Dr. Steenstrup agrees with the view of those zoologists who 
regard the suctorial disk as a modified spinous dorsal fin, Vid. Medd. ntrh. 
Foren. Kjobenh. (1865) 1866, p. 238.

particularly as regards the cranial bones ; it was published before he had an 
opportunity of revising the drawing on the block,
