HELIX. 135 
last whorl, the fourth and fifth on the lower side, all at about equal distances, only the 
second and third somewhat nearer to each other. 
A not full-grown calcified specimen from Uhde’s collection, now in the Berlin 
Museum, is marked “ Vera Cruz”; perhaps it came from the southern part of that 
province, which borders on Tabasco. 
The specific name refers to the rough hairy surface of the shell, the Latin word 
“ coactilia,’ neutr. plur., signifying coarse cloths or felt-coverlets.

E. Mexico: Tuspan, south of Tampico!; Nacimiento de Quilate, Cerro de Espal- 
dilla, and Rancho de Guerrero, all in the environs of Misantla, and Nautla 
(E. Salas *); Chirimoyo, Coatepec, Dos Arroyos, Soncoautia, Consolapa, and 
Barranca de Teocelo, all in the vicinity of Jalapa (#. Salas®); Hacienda de

Distinct from the preceding, H. coactiliata, by its less flattened shape and less 
enlarged umbilicus. In most specimens only one band is to be seen, corresponding to 
the third band of the preceding species but somewhat larger, above the periphery; in 
some examples it is not visible, especially if the hairs are well preserved. A somewhat 
darker hue of the general colour occupies on the upper side the places where the first 
and second bands should be, together with the space between them, and in the same 
manner on the lower side the place of the fourth and fifth bands with the space between 
them, so the general pale colour is limited to the sutural and umbilical regions and a 
small stripe on either side of the (third) band. Strebel® states that he has a calcified 
specimen from Misantla in which the five bands are distinctly present, and Pfeiffer ? 
mentions two bands on the upper side in his H. cordovana, none in his H. suturalis. 
As regards the size, there is also a remarkable variability. Strebel states that his 
largest specimens, up to 11:8 millim. in diameter, are from the environs of Misantla, 
and Pfeiffer gives to his H. cordovana even 124 millim.; the usual size of full- 
grown specimens is diam. 11 millim.
