MOLLUSCA. 635 
Subgen. Hoxospira, s. str. (p. 273). 
See the Monograph of this division by Crosse and Fischer [Journ. de Conch. xl. 
pp. 256-279, t. 5 (1892)], who, however, exaggerate the differences between Holospira 
and Epirobia (cf. anted, p. 283); the gap in the geographical distribution on which 
they rely is now somewhat completed by H. teres, var. hégeana, H. berendti, and 
H. veracruziana. 
Holospira tryoni (p. 276).

2 (a). Holospira veracruziana. 
Holospira (Bostrichocentrum) veracruziana, Dall, Proc. U.S. Nat. Mus. xviii. p. 4 (1895) ’; 
xix. p. 350”. 
Closely resembling the enlarged figure of H. microstoma, Pfr., but with a shorter apical cone and larger 
aperture. 
Long. 174 millim. Whorls 17.

3. Holospira elizabethe. 
Holospira elizabethe, Pilsbry, Proc. Acad. Phil. 1889, p. 89, t. 3. figg. 1-5; Stearns, Proc. U.S. 
Nat. Mus. xii. p. 211 (1890)*; Crosse & Fischer, Journ. de Conch. xl. p. 272, t. 5. 
figg. 6, 6a (1892) *. 
Holospira claviformis, v. Mart. antea, p. 277, t. 16. figg. 10-16 (1897) *. 
Pilsbry’s specimens were from the same locality as mine, and obtained by the same 
collector; the living animal is figured by him !, figg. 3, 5. 
Dall [Proc. U.S. Nat. Mus. xviii. p. 3 (1895)] has proposed for this species a 
subgenus Celostemma, characterized by the axis being vertically ribbed as in 
Colocentrum. 
Holospira pilocerei (p. 278). 
Holospira pilocerei, Crosse & Fischer, Journ. de Conch. xl. p. 265, t. 5. figg. 3, 3.a, 4, 4a (1892) *. 
This species is, in Dall’s arrangement, taken as the type of the subgenus Holospira, 
s. str., characterized by the axis being provided with a plait in the penultimate whorl 
and with basal, parietal, and peripheral lamelle. Crosse and Fischer (loc. cit.) also 
figure a variety of somewhat larger size, figg. 4, 4a, without mentioning a definite 
locality for it.
