Hab. 8. Panama: Isla del Rey (San Miguel), one of the Pearl Islands, and Taboga 
Island, both in the Bay of Panama*, on the trunks of large trees (Cuming 14°). 
This species is described by Broderip! as unicolorous, but Reeve’s® figure shows 
conspicuously darker reddish stripes. Not having seen a specimen, I am unable to 
judge as to its real affinities; but its whole appearance is more like that of Otostomus 
than of the section Leptomerus of Bulimulus. 
Doubtful Species which may belong to this genus. 
1. Bulimus dominicus, Reeve, Conch. Icon. v. t. 78. fig. 6591; Pfr. Monogr. Helic. 
Vivent. iii. p. 4102; iv. p. 4693; vi. p. 1124—Bulimus (Leptomerus) dominicus, 
Pfr, in-Malak. Blatt. ii. p. 159 (1855) °.—Bulimulus (Scutalus) dominicus, Fisch. 
& Crosse, Miss. Scient. Mex., Mollusca, i. p. 540 &—Bulimulus dominicus, Strebel, 
Beitr. Mex. Land- und Siissw.-Conch. iv. t. 6. fig. 17; v. p. 947; Crosse, in Journ. 
de Conch. xxxix. p. 128 (1891) 8. 
Originally stated as coming from San Domingo=Haiti!*, then identified with a 
shell found in East Mexico at Mirador by Berendt‘*, and at Callejon de la Zamorana 
near Vera Cruz by Strebel’, in South-east Mexico at Tabasco by Berendt*, and in 
Chiapas by Ghiesbreght 3°. 
It is improbable that species of this genus should be common to Haiti and Mexico, 
but I cannot make out whether Reeve’s original statement * is erroneous, as Fischer ©, 
Strebel 7, and Crosse® are inclined to think, or Pfeiffer and subsequent authors are 
wrong in identifying them. Perhaps the Mexican examples may be young specimens 
of Otostomus emeus. 
9. Bulimulus albostriatus, Strebel, Beitr. Mex. Land- und Siissw.-Conch. v. p. 94, t. 6. 
fig. 3, probably from Tehuantepec, perhaps collected by Dr. Sumichrast, has also 
the appearance of being a young shell. 
3. Bulimus hachensis, Reeve, Conch. Icon. v., Bulimus, t. 85. fig. 6271; Pfr. Monogr. 
Helic. Vivent. iii. p. 4212.—From Rio Hacha, in Guatemala, according to Reeve: 
I know only a Rio Hacha in Colombia. SB. hachensis bears no near resem- 
blance to any Guatemalan species known to me ; but to judge from the “ delicate” 
appearance and rosy-yellow colour of the shell it may perhaps belong to the group 
of O. sulfureus.
