6 THE NAUTILUS. 



Litiiacella carolinensis (Bosc). 



Liniax carolinensis, Fer. Hist. 77, pi. vi. fig. 3. 



There are two specimens of this species in the British Museum from Virginia 

 {Dr. J. IVyman), agreeing excellently with Ferussac's figure. This slug is cylin- 

 drical, curved, and narrow (in alcohol) ; sole narrow ; ground-colour and colour 

 of sole pale yellow, back thickly marbled with brown-grey, and with tzvo longitu- 

 dinal series of dark egg-shaped spots. Jaw bright-coloured, not ribbed. (De- 

 scription from Brit. Mus. specimens.) 



Dr. Gray (Brit. Mus. Cat.) also describes /,. carolitiensis. 



Limacella nebtdosa. 



? Eiimelus nebulosns, Raf. Ann. of Nat. 1820. 



Tehennophorus carolinensis, Binney, Terr. Moll. U. S. vol. ii. p. 20. 

 This and the last have hitherto been included together under the one name 

 carolinensis, and it is not without misgivings that I venture to separate them 

 here.* Vet, from the specimens which I have examined, there would certainly 

 seem to be a specific distinction between the northern and southern forms referred 

 to carolinensis in the Eastern United States and Canada. The British Museum 

 contains specimens of nebulosa as follows : — 



(1) From Mr. W. G. Binney, labelled T. carolinensis. — Ochreous, marbled 

 with black above, the marblings rather inclined to be in three longitudinal 

 series. Sole unicolorous. 

 (2j W. Canada (Z?/-. Maclagan). — Pale yellow, marbled above with brownish- 

 grey, the markings being a broadish dorsal and narrower lateral brownish- 

 grey bands, with irregular spots over the rest, except sides near foot. Sole 

 unicolorous. 

 (3) Amhurstburgh, Canada West {Dr. O. JV. Maclagan). — Like the last, but 

 mottling grey and more diffuse ; two narrow dorsal and narrowish lateral 

 bands, rather obscurely indicated in grey. Cirey mottling thicker. Ground- 

 colcur pale yellowish. 



Comparing carolinensis with nebulosa, we note : — 



(rt) The Virginia carolinensis. — Sole narrow, yellowish, pale, without trans- 

 verse strice; body smoothisii. 



{b) nebulosa, uo. 1 above. — Sole broad, brown, with strong transverse stria;; 

 body rugose. 



Or, taking measurements : — 



(rt) Tiie Virginia carolinensis. — Long. 35 millim., sole, lat. 3 millim. 

 [b) nebulosa, no. 1 above. — Long. 35 millim., sole, lat. 7^ millim. 

 (f) nebulosa, no. 2 above. — Long. 36 millim., sole, lat. 8 millim. 

 Rafinesque described five supposed species belonging to Philoinycus and 

 Eumelus in 1820 as quadrilus, oxurus, Jlexuolaris, fuscus, and lividus. They 



*Mr. W. Binney writes {in lilt. Sept.' 9, 1890) : — " I am rather sceptical about 

 there being two species .... as you say . . . . — there is a big species of Tehen- 

 nophorus confounded with carolinensis, but having a ribbed jaw."
