GLANDINA (p. 46). 
Glandina sowerbyana (p. 55). 
Glandina sowerbyana, Biolley, Mol. terr. y fluv. de Costa Rica, p. 5 (1897). 
To the localities given, add :— 
Hab. N.E. Costa Rica: San Carlos and Sarapiqui (Biolley 8); Puerto Viejo, at the 
foot of trees (Biolley). | 
[E. Costa Rica :] Turrialba and Reventazon, 500 metres (Biolley 18). 
CENTRAL Costa Rica: San José, 1161 metres (Biolley 1). 
S.W. Costa Rica: Turubares, 250 metres (Biolley 8); Alto de Mano Tigre, 
690 metres, and Terraba, 200-300 metres (Pittier, 1891); El Pital, in the 
valley of the Rio Naranjo (Pittier, 1893). 
Biolley 18 states that this species, the largest and finest of the genus found in Costa 
Rica, chiefly inhabits the “ tierra caliente,” and that all the specimens from the elevated 
central plain are of smaller size, however full-grown, measuring only 35-40 millim. in 
length. 
Glandina coulteri (p. 56). 
Biolley (/oc. cit. p. 6) enumerates this species also from Costa Rica. This is probably 
an error in determination, as I have never seen a specimen of it among the various 
representatives of the genus collected by himself and sent to me for determination by 
P. Godet of Neufchatel. 
6 (a). Glandina michoacanensis. 
Glandina michoacanensis, Pilsbry, Proc. Acad. Phil. 1899, p. 397°. 
“‘ Obesely fusiform, coarsely and irregularly plicate and finely plicatulate longitudinally, the foldlets cut into 
oblong grains; dark dull reddish, with an irregular pale sutural border.” 
Long. 48°5, diam. 20°5, apert. 25-7 millim. 
Hab. CENTRAL Mexico: Uruapam, State of Michoacan (Mr. & Mrs. Rhoads), 
Glandina ghiesbreghti (p. 58). 
Glandina ghiesbreghti, Pilsbry, Proc. Acad. Phil. 1892, p. 338°; and in Nautilus, xiii. p. 1397. 
To the locality given, add :— 
Hab. 8.E. Mexico: San Juan Bautista in Tabasco (Rovirosa 6 ), 
Glandina decussata (p. 58). 
Pilsbry [ Nautilus, x. p. 59 (1896)] mentions a species of the decussata-group of this 
genus, not adult, found by Prof. Townsend at San Rafael, Jicaltepec, Vera Cruz: this 
may belong to Strebel’s @. ¢ened/a. Stearns [Proc. U.S. Nat. Mus. xiv. p. 95 (1891)]
