ON A NEW SPECIES OF SEPJOLA. 



MM. Gervais and Vanbeneben have lately presented to the Acad, 

 des Scienc. de Bruxelles a memoir on the genus Sepiola, and in a 

 subsequent note have described a new species under the name of 

 macrosoma from the Bay of Naples, and figured in Delia Chiaje's 

 * Memorie sugli animali senza vertebre/ pi. 71. fig. 1 — 2. The most 

 remarkable fact found by the authors in examining this species was 

 the existence of an inferior eyelid, which in a certain degree calls 

 to mind the principal character on which R. Owen established his 

 Rossia palpebrosa. The Sep. macrosoma has moreover in common 

 with this a very extraordinary size. It would perhaps be necessary, 

 did we not place entire confidence in the accurate descriptions of the 

 learned Englishman, to compare individuals of the two species. How- 

 ever their geographical distribution alone would authorize their se- 

 paration, the one having been discovered by Capt. Ross at the Arctic 

 Pole, while our species inhabits the Bay of Naples. 



The body is globular and perfectly rounded at its posterior part. 

 The arms are placed about middle way, they are by some lines closer 

 together beneath than above. The mantle does not present any point 

 of adhesion with the body in its inferior or anal portion ; it is only 

 at the nuchal or superior part that a junction of a small extent is 

 perceived. The dorsal plate is larger in front than behind, and gra- 

 dually becomes narrow. It is undoubtedly the largest species of the 

 genus. If we compare it with the S. palpebrosa we first see the 

 eye-ball protected by a palpebral fold in both species, but in the 

 northern one the eyelids completely hide the eyes, and there exists 

 one above and one below, although the latter is the largest. In 

 our species we cannot find a trace of any superior eyelid, conse- 

 quently the eye is not completely closed. 



R. Owen supposes that these eyelids serve the species inhabiting 

 the cold countries to protect the eye-ball against the fragments of 

 ice, but the existence of eyelids in a Neapolitan species necessarily 

 destroys this supposition. 



The body is much less elongated in our species, and the arms are 

 not inserted so near the front margin of the mantle, they are also 

 perfectly rounded. The arms have the same proportions in the two 

 species, with this exception, that in the northern species the third 

 pair surpasses the fourth considerably. The tentacula are longer in 

 the Neapolitan species.
