602 SUPPLEMENT. 
HELICINA (p. 28). 
My subdivision I., Carinate, of this genus (anted, p. 28) is named Ozxyrhombus by 
Fischer and Crosse [Miss. Scient. Mex., Moll. p. 399 (1893)]; Il., Rostrate (antea, 
p- 30), Caloplisma (of. Fisch. & Crosse, loc. cit. p. 405); and V., Llate trochiformes, 
Pyrgodomus (cf. Fisch. & Crosse, loc. cit. p. 440). It may be noted here that the 
anatomical characters of the family Helicinide are also given by these authors (loc. cit. 
pp. 390-398). 
Helicina ghiesbreghti (p. 28). 
Helicina ghiesbreghti, Fischer & Crosse, Miss. Scient. Mex., Moll. ii. p. 399, t. 55. figg. 5,5 a-c’; 
Pilsbry, Proc. Acad. Phil. 1892, p. 389°. 
To the localities given, add :— 
Hab. [S.B. Mexico:] Mountains of Poana, Tabasco » (Rovirosa 6), 
Fischer and Crosse ®, evidently by mistake, quote the localities “ Honduras,” “ Nica- 
ragua,” and “ Bugaba, Panama,” given by myself for H. amena and its varieties, under 
this species. 
Helicina amena (p. 28). 
Helicina amena, Fischer & Crosse, Miss. Scient. Mex., Moll. ii. p. 401, t. 55. figg. 3,3 a-c, and 4" ; 
Ancey, Ann. de Malac. ii. p. 259 (1886) ”. 
To the localities given, add :— 
Hab. [Honpuras:] Island of Utila (Simpson 1), 
Helicina sowerbyana (p. 28). 
Helicina sowerbyana, Fisch. & Crosse, Miss. Scient. Mex., Moll. i. p. 444%. 
These authors doubt the validity of this species, as well as its supposed locality, 
Guatemala. 
Helicina cinctella (p. 29). 
Helicina cinctella, Fischer & Crosse, Miss. Scient. Mex., Moll. ii. p. 403, t. 55. figg. 6, 6 a—c, and 
7, 7a-c*; Pilsbry, Proc. Acad. Phil. 1891, p. 332°. 
To the localities given, add :— 
Hab. [E. Mexico:] Orizaba® (Hetlprin, 1890 °). 
Fischer and Crosse distinguish two forms of this species—cinctella, var. 6, Pfr. 
(Monogr. Pneum. Vivent. ii. p. 216), and var. botteriana, Pfr. (their fig. 7); but as the 
differences are very slight and gradual, and the localities are the same, they can 
scarcely be regarded as anything more than individual variations.
