We have several metatypes collected by Gabb in Santo Do- 

 mingo. The apex is always eroded. Guppy erroneously referred 

 this species to the fluviatile, Malayan genus Clea H. and A. 

 Adams. E. truncata is the genotype and sole species of Gabb's 

 Ectracheliza. 



Genus Columbella Lamarck 



Subgenus Mela Reeve 



Meta islahispaniolce ;, n. sp. 



Plate 15, Figure 3 



Shell small, coniform, spire very acute, suture distinct, 

 whorls eight, the first two smooth, nuclear, horn-colored or 

 glassy; first three post-nuclear whorls ornamented with longitu- 

 dinal riblets, eight or ten to each volution, giving them a coro- 

 nate aspect; these riblets then entirely fade out, so that the last 

 three whorls of the spire are smooth except for arcuate growth- 

 lines, and are channeled ; body-whorl with a shoulder carina and 

 marked anteriorly by a varying number of incised lines, there 

 being on one shell only six near the base, but on the other 

 about twenty, extending almost to the center of the whorl; aper- 

 ture very narrow; inner lip with a thickening at the center; 

 outer lip thickened externally, the thickening slightly plicated 

 at the base, margin of lip thin, bearing within about fifteen 

 short lirae; anterior sinus rounded, posterior U-shaped, situated 

 above the shoulder carina. Length 1 1 , width 6 mm. 



This rare shell appears to be referable to the genus Meta.
