338 REV. R. BOba watsoit on the 



carina of T. carinifera, I am persuaded tliat Lamarck had before 

 him the Pacific species. That species differs from F. maderensis 

 in beiug ruddy inside and outside ; it lacks the two little teeth on 

 outer and inner lip at the origin of the canal ; the junction of 

 snout and base is much more strangulated ,; there is a much 

 stronger basal carina; the mouth is more open, the outer lip 

 being much more patulous ; the snout is not so regularly 

 attenuated ; the longitudinal ribs are more numerous and rise 

 more roundly, not being flattened horizontally and pointed ; the 

 shoulder below the suture is less drooping, and the outer lip joins 

 the body at the third, not at the second carinal spiral, tlius leaving 

 two, not merely one, spiral threads on the earlier whorls. 



F. lirpiaria, L., a Mediterranean species, is a much narrower 

 form, of stouter build, broader in the snout, and quite differently 

 ribbed and spiralled. I should have liked to compare this Atlantic 

 species witb Turlinella remvirostra, Wagner. The differences 

 are obvious enough on the surface ; but I do not know the species 

 well enough to judge how far these a,ve constant. I have with 

 much hesitation described this as a new species, thinking so well 

 known a form must have been already published ; but, after much 

 inquiry, I have quite failed to identify it. My reason for calling 

 it maderensis is that I have long had it from Madeira, and I am 

 not quite sure whether my Cliascax maderensis is not a very aber- 

 rant variety. The enormous umbilicus of that species is certainly 

 very striking ; and the total absence of teeth, not only on the outer 

 lip, but even on the pillar, is a further notable feature of difference 

 ' — a feature so notable that I think my friend Dr, Kobelt, had the 

 shell itself been before him, would hardly have suppressed Chascax 

 as a mere Fasciolaria. Still, withal, while protesting against 

 hasty judgment, I feel it is possible that Ghascax maderensis and 

 the present form may ultimately prove to be one species; and in 

 that case it will be an advantage that they have the same specific 

 name.
