186 EUGLANDINA. 



darker red on the spire, more yellowish towards the base, the 

 suture with a pale border about 1.5 to 2 mm. wide on the 

 last whorl, surface somewhat glossy, sculptured with coarse 

 irregular plicae, strongest near the suture, which they irreg- 

 ularly crenulate, and with finer folds which are cut into ob- 

 long grains in spiral series, as in E. vanuxemensis. This 

 sculpture becomes weaker below the middle of the last whorl 

 and is obsolete at the extreme base. The spire is conic with 

 quite obtuse apex. The first 21/2 whorls are smooth and mod- 

 erately convex ; then vertical riblets begin, very weak at first, 

 but becoming strong and regular, with smooth intervals; at 

 the end of 3% whorls, marking the limit of the embryonic 

 stage, the whorl widens more rapidly and the woven sculpture- 

 pattern of the adult stage begins. The aperture is rather 

 small, slightly oblique ; outer lip hardly arching forward. 

 The columella is only slightly concave either in front or pro- 

 file views, and is abruptly truncate basally. Length 49.6, 

 diam. 21.2, length of aperture 26 mm. ; whorls 7%.

This fine species has sculpture like E. vanuxemensis, but it 

 differs from that by its smaller aperture, less concave colu- 

 mella, and especially by the embryonic shell, which has a 

 long smooth-ribbed stage, and consists of more whorls than 

 that of E. vanuxemensis. The type specimen is described 

 and figured.

Shell oblong-conic, thin, longitudinally plicate and decus- 

 sated with close spiral striae, flesh-colored irregularly marked 

 with non-projecting brown-margined white varices. Spire 

 conic, rather obtuse; suture elegantly crenulate with white. 

 Whorls 8, slightly convex, the last a little longer than the 

 spire, longitudinally striated below the middle, not decussate
