Colombia: Bogota. 



Glandina bogotensis DA C., Proc. Malac. Soc. Lond., vi, p. 



6. pi. 1, f. 5 (March, 1904). 



"It is closely allied 'to G. aquatoria Da Costa, from Ecua- 

 dor, but is more fusiform, thinner, has a whorl less, and is 

 without the transverse striation of that species. ' '

Vol. I, p. 39. There are 3% embryonic whorls, the first 

 two smooth; then very fine, close and delicate striae appear 

 below the suture, gradually increasing in length until on the 

 last embryonic half whorl they extend to the suture below. 

 The neanic and adult sculpture consists of rather coarse rib- 

 lets occasionally forked, and on the last whorl about seven to 

 ten in the space of 5 mm. An impressed subsutural groove 

 cuts the riblets, defining a distinct margin about 1 mm. wide, 

 with sculpture of oblong granules, each formed by the end of 

 a riblet. The suture itself is irregularly crenulate. At the 

 periphery the riblets rather abruptly fade out, leaving a much 

 smoother, only irregularly and very weakly plicatulate base. 

 Very dense and fine incised spiral lines cover the last whorl 

 throughout; on the penult, whorl they are weaker, and are 

 nearly lost on earlier whorls. The columella is nearly straight, 

 and the outer lip has a whitish edge. The specimen figured 

 measures, alt. 55.3, diam. 24.3, aperture 27 mm. long, with 7 

 whorls. Pfeiffer 's type is 56x24 mm. Ecuador. 



8. E. ECUADORIANA (Miller). Vol. I, p. 40. 



Related to E. saccata, but much more delicately plicatulate, 

 with much finer spiral striation; suture coarsely crenulate, 

 each granule occupying the breadth of two folds. The folds 

 fork near the middle of the last whorl. 62x26 mm., aper- 

 ture 30x12 mm. Val de Pilaton, Ecuador. 



9. E. ^QUATOBIA (Da Costa). PI. 20, fig. 9. 



Shell fusiform-oblong, rather thick, glossy, purplish-chest- 

 nut; whorls 6, a little convex, longitudinally very closely 

 plicate-striate, under the lens minutely transversely striate, at
