90 LATIRUS. 



L. attenuatus, Reeve (figs. 122, 144), appears to be founded on 

 a young shell of the above, 



L, FILOSUS, Schubert and Wagner, PI, 68, fig. 128. 

 Whitish, the narrow revolving ridges chestnut-brown. 



Length, 1*5 to 2*25 inches. 



Prince's Isl. ; Senegal. 



L. LYRATUS, Reeve. PI, 61, fig. 123 ; PI. 68, fig, 145, 

 Rufous-brown, lighter on the ribs. Length, 1*75 inches. 



Philippine Isles. 



Kobelt (in Kiister, Conch. Cab.) considers this = Fusus con- 

 strictus Koch, which was published during the same year. The 

 latter I have referred to Coralliophila, because the figure and de- 

 scription afford no evidence of columellar plaits, and the umbilical 

 fasciole is fringed as in that genus. 



L. MODESTUS, Anton. PI. 68, figs. 129, 130, 142. 



Reddish yellow, revolving cords sometimes darker ; sutures 



frilled. Length, 1-85 inches. 



Panama to Acapulco. 



Described as a Fusus, without locality, and said to have no 

 plaits on the columella; it has the facies of a Latirus, however, 

 and appears to be nearty allied to the preceding species. 



L. spadiceuSj Reeve (fig. 130) can scarcely be distinguished 

 as a different species. The latter is said by C. B. Adams to oc- 

 cur at Panama. I include also L.concentricus, Reeve (fig. 142), 

 which occurs at St. Elena and Acapulco. 



L. LANCEOLATUS, Reeve. PL 68, fig. 132. 



Light yellowish brown, darker beneath the periphery ; violet 

 within the aperture Length, M5 inches, 



Philippine Is. on the sands. Cuming. 



L. LANCEA, Gmel. PI, 68, figs. 133-135. 



Yellowish brown, the interstices of the longitudinal ribs chest- 

 nut brown. Length, 2 inches, 



Isle of Ticao, Philippines ; Indian Ocean. 



Fusus aeus, Ad. and Reeve (see p, 63, t. 38, f. 160) is almost 

 certainly a synonym.
