381. iaterculata (f. 651), Sowerly. — Testa fusiformis, 

 cancellata, spira longitudine aperturam asquanti, anfractibus 

 augnlatis ; ultimo antice acuminato, fascia lata, maculis 

 laterculiforrnibus, bimarginatis cincta, medio ornata ; aper- 

 tura intiis lirata. — Shell fusiform, cancellated; spire as 

 long as the aperture ; whorls angular, the last acuminated 

 anteriorly, ornamented in the middle with a broad band 

 bordered at each edge with tile-like spots ; aperture ridged 

 within. 



382. speeta (f. 648), B. M. — A singularly characterized 

 minute shell. 



383. abenosa (f. 422, 423, 426, 427), Lamarck.— These 

 figures represent the principal variations of this species, 

 which may perhaps correctly be distinguished from M. 

 exasperata by the ribs being much closer, and the whole 

 sculpture closer. 



384. exasperata (f. 419, 424, 425), Chemnitz. — See pre- 

 ceding. 



385. fidicula (f. 598), Gould. 



386. buccinoidea (f. 411), Sowerby. — Testa parva, ovata, 

 subccerulea, fascia alba inter fasciis fuscis duabus medio 

 anfractuum cincta, costis longitudinalibus subarcuatis, nu- 

 merosis, et striis spiralibus sculpta ; spira acumiuata, aper- 

 turam longitudine asquanti ; apertura intus bifasciata, canali 

 antico brevi. — Shell small, blueish, having two chestnut 

 bands near the middle of the whorls, with a white one 

 between them, sculptured with numerous bent longitudinal 

 ribs and spiral strise ; spire acuminated, about equal to 

 aperture in length ; aperture internally banded, ending in 

 a short canal. 



Sect. XIII. Elongated, fusiform, longitudinalhj ribbed, 

 mouth generally ribbed within. Includes a large portion 

 of the genus tuebicula as adopted by some conchologists. 



387. regina (f. 53), Sowerby, " Genera of Shells." 



388. t^niata (f. 51, 52), Lamarck. — The whorls are not 

 angular, as in 31. regina.
