The Collared Snake (Coluber natrix) in the Sea. 
By Dr. J. E. Gray, F.R.S. 
It has been stated by several persons that Sea-Snakes are some- 
times found in the European seas, and even on English coasts, as far 
north as the Orkneys, their appearance in the latter locality being 
accounted for by their haying been carried there by the Gulf-stream, 
which might perhaps happen with some American species; but the 
specimens shown to me haye all been the common Collared Snake 
(Coluber natriv), and I have been inclined to doubt the accuracy of 
the statements, as they were not well authenticated, and on exami- 
nation were generally found to have come through two or more 
persons before they reached me. The other day the Secretary of the 
Montrose Natural History Society showed me a specimen of Coluber 
natri# which was taken up in a bucket in the sea, about twenty-five 
miles from the Naze on the coast of Norway. It lived some time 
aboard, and arrived alive at Montrose and was there put in spirits. 
This Snake is aquatic in its habits, often found in ponds and 
ditches, where it goes to catch frogs, fish, &e. It has no near rela- 
tion to what are usually called Sea-Snakes (Hydride). This Colu- 
ber may have been washed down by the floods into the sea, as the 
Boas are said by Guilding to be in the West Indies. 
On the Jaw of Cylindrella. By T. Brann. 
42 Pine Street, New York, 12th October, 1868, 
My Dear Srr,—I have lately made an unlooked-for discovery, 
which I announce to you, to whom all are so much indebted for 
labours with reference to classification. 
I find that Cylindrella, as well as Macroceramus, has a jaw, in 
both of much the same character. Lately I received several species 
either alive or in glycerine; and immersion in a solution of caustic 
potash enabled me with comparative ease to detect the jaw. Being 
very minute and delicate, I do not wonder at this having escaped 
notice. I had previously examined dead and dried-up specimens 
only of the Cylindrella-Maugei group. 
I have both jaws and lingual bands of 
Cylindrella sanguinea, Pf. C. gracilis, Wood. Jamaica. 
Jamaica, C. Maugei, Wood. Jamaica. 
C. rosea, Pf. Jamaica. C. trinitaria, nu. sp. Trinidad. 
C. brevis, Pf. Jamaica. C. bahamensis, n. sp. New 
C. elongata, Ch. Jamaica. Providence. 
I shall publish this with figures; meantime I take pleasure in in- 
forming you, as I have Dr. Pfeiffer, through Mr. Crosse. 
I am, my dear Sir, 
Dr. John E. Gray, Very truly yours, 
British Museum. T. Brann. 
Remarks on the Development of Marine Fishes. By G. O. Sars. 
It has long been supposed that the codfish deposit their ova at 
the bottom of the sea. M.G. 0, Sars has recently shown that this
