MANGILIA. 247 
M. Guarant, d’Orbigny. Pl. 22, fig. 46; Pl. 18, fig. 21. 
Brownish, sometimes with narrow, lighter bands; ribs promi- 
nent, rounded, crenulating the suture; there are elevated 
revolving lines. Length, 5 mill. 
West Indies (Reeve), Brazil (d’Orb.). 
M. obesicostata, Reeve (PI. 18, fig. 21), from the West Indies is 
evidently a synonym. 
M. Dysont, Reeve. PI. 21, fig. 27. 
Whitish, with two faint bands of orange-brown. Length, 9 mill. 
Honduras (Dyson). 
M. syMMETRICA, Reeve. PI. 21, fig. 40. 
Whorls shouldered; longitudinally ribbed, the interspaces 
with very fine elevated strie; yellowish brown, the shoulder 
white. Length, 5 mill. 
Habitat unknown (Mus. Cuming). 
I can add nothing to the information concerning this species. 
M. BALTEATA, Reeve. PI. 24, fig. 11. 
Whorls obtusely slightly angulated in the middle; ribs few, 
narrow, with wide smooth interspaces; white, with a median 
chestnut zone. Length, 12 mill. 
Habitat’? (Reeve), West Indies (Swift). 
Krebs considers MM. densestriata, C. B Ad., a doubtful 
synonym; it isa white shell, without band, ribs 10 to 12, more 
numerous than in the figure of balteata, the interstices very 
finely striate transversely. I am not acquainted with the species, 
but the characters appear to be sufficiently distinctive. Brazier 
identifies an Australian shell with MW. balteata. 
M. BADIA, Reeve. PI. 21, fig. 41. 
Shell plicately ribbed, transversely strongly plicated; dark 
chestnut-brown. Length, 5 mill. 
Habitat? (Reeve), St. Thomas, W. I. (Krebs). 
According to Krebs, M. crassicostata, C. B. Ad. (an unfigured 
Species), is a Synonym. 
M. ramineata, C. B. Adams. PI. 21, fig. 31; Pl. 18, fig. 36. 
Shell narrowly shouldered, with small, close, numerous longi-
