MANGILIA. 24? 



M. GUARANI, d'Orbigny. PI. 22, fig. 46 ; PL 18, fig. 21. 



Brownish, sometimes with narrow, lighter bands ; ribs promi- 

 nent, rounded, crenulating the suture 4 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. DYSONI, Reeve. PI. 21, fig. 21. 



Whitish, with two faint bands of orange-brown. Length, 9 mill. 



Honduras (Dyson). 

 M. SYMMETEICA, Reeve. PL 21, fig. 40. 



Whorls shouldered ; longitudinally ribbed, the interspaces 

 with very fine elevated stride ; 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 M. densestriata, C. B Ad., a doubtful 

 synonym ; it is a 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 M. balteata. 



M. BADIA, Reeve. PL 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. TRILINEATA, C. B. Adams. PL 21, fig. 31 ; PL 18, fig. 36. 

 Shell narrowly shouldered, with small, close, numerous longi-
