298 ANTILLEAN LEPTINARIA. 



5a. Var. ABDITA (Poey). PI. 44, figs. 57, 58. 



Shell imperf orate, turrite-subulate, the apex rather acute; 

 delicately striate, rather glossy, whitish. Whorls 6, a little 

 convex. Columella arcuate, obliquely truncate. Aperture 

 oval-oblong, angular above ; peristome simple, acute, the right 

 margin outwardly somewhat produced, columellar having a 

 truncation. Length 5.66, diam. 2, aperture 1.66 mm. long, 

 nearly 1 mm. wide (Poey). 



Cuba: Almendares (Gundlach, type loc.), and Marianao 

 (Rhoads), both near Havana. Santiago (Gundlach).

"Apex as in 8. goodalli; related to 8. striosa Ad., but more 

 slender. 8. subulaioides Orb., from the description and fig- 

 ure, appears to differ by being more striate, narrower, with 

 a different aperture " (Poey). 



Poey's poor original figure is copied, fig. 57. One of a 

 large series from Marianao, near Havana, is figured, fig. 58. 

 The shell is clear whitish-corneous, translucent, and smooth 

 except for weak strias. The outer lip bends forward a little 

 near the upper insertion. The columella is concave above 

 and obliquely truncate below, its base 'being a rather acute, 

 spirally-entering lamella. Length 6, diam. 2.1, aperture 2 

 mm., whorls 7. Most of the specimens contain several large 

 eggs, showing yellowish through the shell. 



This form tapers slightly more than the small form of L. 

 striosa from Jamaica and Haiti, but the difference is so slight 

 that I have not much doubt of their identity. It would be 

 quite impossible to separate the shells if they were mixed. 



L. ROBERTSI Pilsbry, n. sp. Pi. 50, figs. 19, 20, 21. 



Shell slender, turrite, imperf orate, thin, whitish-corneous, 

 smooth, very faintly traced growth-lines visible only when 

 highly magnified ; somewhat glossy. Summit obtuse, rounded. 

 Whorls 6%, convex, the last one slightly less so. Aperture 

 vertical, rhombic-ovate, the thin outer lip moderately arched
