TURBO. 841 



Turbo eburneus. Walkers Min. Shells, f. 36. Adams's 

 Micros, p. 637. t. 14. f. 15. 



Inhabits the coasts of Great Britain. Walker, 8fc. 



Shell about an eighth of an inch long, and one-third as broad, 

 of a pale horn-colour, but appears black when the animal is 

 in it ; it is nearly allied to T. Ulvce, but differs in having the 

 whirls ventricose, and in being glossy, much thinner, and of 

 a paler colour. 



SUBUMBILICATUS. 59. Shell conical, minute, sub- 

 iimbilicated, with four or five tumid whirls, 

 and the aperture completely ovate. 



Turbo subumbilicatus. Montagu Test. p. 316. Matonand 

 Racket, in Lin. Trans, viii. p. J 65. Dorset Cat. p. 50. 

 t. 18. f. 12 b. 

 Inhabits the shore at Weymouth. Montagu. 

 Shell one-eighth of an inch long, and half as broad, smooth, 

 somewhat glossy, and of a yellowish white colour ; the greater 

 proportional breadth of the body-whirl readily distinguishes 

 this species from both T. Ulvce and T. ventrosus, and the 

 aperture is not contracted into an angle at the upper end. 



CINGILLUS. 60. Shell conical, minute, with six 

 flattish slightly striated contiguous whirls, 

 and alternate bands of chestnut-brown and 

 horn-colour.

 Turbo vittatus. Donovan, v, t. 178. f. 1. 

 Inhabits the coasts of Great Britain. Montagu, Sfc, 

 Shell rather more than an eighth of an inch long, and one-third 

 as broad ; it somewhat resembles T. unifasciatus, but Mr. 

 Montagu says it may be distinguished " by having the outer 

 lip in a line with the shell, not turning outward ; by the 

 brown bands being darker,' and the intermediate space not 

 so white ; and in live shells by the spiral stria?, which are 

 strong at the base ; it is also a more slender shell." 



;iNTERRUPTUS. 61. Shell conical, minute, acumi- 

 nated, with five Hattish whirls, and interrupt- 

 ed longitudinal yellowish brown streaks. 



Turbo interruptus. Adams in Lin. Trans, v. p. 3. t. 1. f.
