186 Mr. J. G. Jeffreys on the Marine Testacea 



three-eighths of an inch in length, and nearly one-sixth in their 

 extreme breadth. A half-grown specimen is in the British Museum, 

 among the shells collected at Lisbon by Mr. MacAndrew ; and I 

 before noticed it in the * Annals' as an Adriatic species. — O. acuta,

Eulimella striatula, n. s. PI. II. f. 14, 15. 



Testa subcylindrica, aciculata, hyalina, limo partim induta ; anfrac- 

 tibus 8-9, complanatis, ultimo tertiam spirse partem subeequante, 

 concentrice confertim rugoso-striatis ; sutura distincta, obliqua ; 

 apertura oblonga-rhomboidea, supra acutangulata, infra latiore, 

 subtruncata ; columella flexuosa ; long. y\j, lat. ^ unciee. 



I took two live specimens of this very distinct shell by dredging in 

 about 10 fathoms at Spezia. It is more delicate than Eulimella aci- 

 cula, and has the volutions more flattened, the suture more oblique, 

 and the last whorl and aperture proportionably longer ; and it espe- 

 cially differs in having distinct undulating transverse strise. All the 

 species of Eulimella exhibit under a microscope similar, but very 

 faint, and close-set, striae. One of the characters assigned to the 

 genus Eulimella by its founder (Professor Edward Forbes) is " solid, 

 smooth, and polished ;" so that either this character must be ex- 

 punged, or the genus merged in Odostomia or Chemnitzia.
