Oleacina albersi, Pfr. Monogr. Helic. Vivent. iv. p. 6407. 
Var. inflata. (Fig. 11.) 
Magis ventricosa, spira breviore, columella paullo magis arcuata. Long. 273, diam. 13, apert. 11 millim. 
Hab. N.W. Mexico; Mazatlan (Reigen?); Mazatlan and Tres Marias Islands (Forrer ; 
specimens in the Berlin Museum, 33 millim, long.); Sierra Madre de Colima 
(Xantus°); Tepic (Richardson; typical form and var. inflata). 
The original locality given by Pfeiffer! is the “ Gulf of California.” The additional 
habitat ‘“Tumaco” (in Ecuador) (Albers, Die Helic. ed. 2, p. 27) is founded on a 
label in the collection of the late Mr. Albers upon the authority of Cuming, and is very 
probably an error. 
By some authors this Glandina seems to have been confounded or combined with 
much more elongated species from the same country, such as G. turris and G. excavata. 
44. Glandina mitriformis.

In outline this shell resembles G. alberst ; I have not seen a specimen of it.
