EUCALODIUM. 259 
are found in this species, as well as in E. walpoleanun.. Transverse dark brown spots 
in the interstices occur also here and there in both species. 
The locality “ Colombia ” given by Sowerby is no doubt incorrect.

Very near E.. blandianum, resembling it in size and colour, but somewhat more 
slender and often of a darker brownish tint; the chief difference, however, is in the 
sculpture, £. walpoleanum having more numerous and more feeble coste, with the 
interstices often not twice their width, and distinctly transversely striate, the strie 
continued more or less on the costa themselves, these latter generally being of the 
same colour as the interstices. The last whorl is angulated at the base, but the angle 
disappears more or less near the aperture. Number of remaining whorls in the full- 
grown shell 9-12. 
In the Berlin Museum there is a specimen of this species which has been fractured 
during life and restored, in which the aperture does not exceed the suture, the 
columellar margin is rather distinctly toothed, and the basal edge is unusually strong. 
Several other specimens show a raised spiral line somewhat beneath the suture, or 
midway between the upper and lower suture in some of the terminal whorls and even 
in the last, but not regularly and in different degrees of strength. | 
Fischer and Crosse mention ® a small variety from Guatemala; and Strebel (Beitr. 
Mex. Land- und Siissw.-Conch. iv. p. 68, t. 7. fig. 3) a form ‘*B,” based upon specimens | 
found at Miahuatlan, in Eastern Mexico, in company with EL. blandianum, resembling 
‘ the latter in colour and gloss and in the strength of the coste, but having the trans- 
verse striated sculpture of L. walpoleanum.
