NOTES ON THE GENUS CARINARIA, WITH AN ENUMERATION OF 

 THE SPECIES, AND THE DESCRIPTION OF A NEW FORM. 



By G. B. SoAVEiiBY, F.L.S. 



Read May Vlth, 1893. 



Of tlie genus Carinaria only two species are at all generally known. 

 These ai'e the large and highly valued C. ritrea^ Lam. {Patella 

 cnstata, Linn.), and the much commoner Mediterranean species C. 

 Mediterranea, Desh. {=C. Lainarckii, Peron and Lesucur). A third 

 form is figured in the " Thesaurus," C. Atlantica, Adams and Reeve, 

 hut although it is described as not uncommon in the jS^orth Atlantic 

 it is but little known, and has probably never been taken since the 

 voyage of the " Samarang." A mistake has been made in the 

 "Thesaurus" in giving the name C. Cristata, Linn., for C. Mediter- 

 ranean instead of for C. vitrea. 



ENTmEEATION OF THE SpECIES. 



1. Carinakia cristata, Linn. [Patella). Linnaeus Syst. Nat. cd. 12, 

 p. 1260. 



= Argonaitta vitrea, Gmelin. Linn. Syst. Nat. ed. 13, p. 3368. 



= Carinaria vitrea, Lamarck, Syst. Anim. p. 99. 



This is by far the largest species of the genus. Specimens of the 

 shell come occasionally, but very rarely from Amboina. If the animal 

 bears the same proportion to its shell as does that of C. Lamarckii it 

 must be something like two feet long. 



2. Carinaria La:marckii, Peron et Lcsueur, Ann. du Mus. vol. xv., 

 p. 69, pi. 3, fig. 15. 



= d. Mediterranea, Sowerby, Recent et Fossil Shells, pi. 279. 



= G. cymbium, Woodward, Mem. Moll. p. 200, fig. 105, non 

 Argonauta cymliiim Lamarck. 



= C. fragilis, Reeve, Conch. Icon. Carinaria, pi. 1, species 1 [non 

 Bory St. Vincent). This is the commonest known species, and is 

 found so far as I know exclusively in the Mediterranean Sea. 



3. Carinaria Atlantica, Adams and Reeve, Voyage of the 

 "Samarang," Moll. p. 63, pi. 13, fig. 12. The shell of this little 

 species is somewhat like that of C. Lamarchii, but shorter and more 

 curved. The animal is very different ; the body is extremely narrow 

 and cylindrical, whilst the head seems very distinct, and according 

 to the figure looks like that of a walrus, with the short tentacles 

 for tusks. 



4. Carinaria Australis, Quoy and Gaimard, Voy. de I'Astrolabe, 

 voL ii., p. 394, pi. 29, figs. 9-13. 



The shell of this species differs very little from that of C. 

 Lamarckii. It is said to be more elongated and less elevated, 

 with the back more curved. The animal seems to differ principally 

 in the form of the swimmer, which is quadrilateral instead of 

 rounded.
