GLANDINA. 67 
Type now in the British Museum, Rather near to G. simplex, but distinct by the 
nearly straight columella. I am indebted to Mr. Edgar Smith for furnishing me with 
a figure of it (fig. 8). 
24. Glandina excavata, sp. n. (Tab. IV. tigg. 9, 9 a.) 
Glandina albersi (Pfr.), Binney, Land and Freshw. Shells of N. Am. i. p. 18, fig. 9 (not the 
description) ’. 
Testa subcylindrica, confertim striatula, striis in anfractu ultimo levioribus et magis irregularibus, sculptura 
spirali vix oculo armato conspicua, nitidula; anfr. 6, priores obesi convexiusculi, penultimus et ultimus 
subplani, apex obtusus ; sutura subsimplex, albida vel pallide grisea ; apertura piriformi-lanceolata, dimi- 
diam teste longitudinem vix squans, margine externo subperpendiculari, antrorsum leviter convexo, 
columella in medio excavato-arcuata, deorsum laminiformi, spiratim contorta, transversim truncata. 
Long. 31, diam. 114; apert. long. 16, diam. 6 millim. 
Hab. N.W. Mexico: ? Mazatlan. 
I have three specimens before me—two from Prof. W. Dunker’s collection, marked 
G. turris, Mazatlan (fig. 9), and one from Mr. Patel’s collection labelled G. albersi, 
Peru ; the real habitat of G. excavata is therefore quite uncertain. Nevertheless I do 
not like to omit this species, as it is very similar in its general form to G. pseudoturris, 
but quite distinct by the columella and also by colour. 
The figure given by Binney! represents G. excavata rather well, both in the general 
shape and in the peculiar conformation of the columella. It is said to have been 
drawn from an authentic specimen of G. albersi in Cuming’s collection; but it does 
not agree with the original description by Pfeiffer, who says “ testa ovato-oblonga” 
and “ columella substricte descendens,” nor even with that of Binney, which is a trans- 
lation of that given by Pfeiffer. |
