TEREBRA.— Plate XVIII. 



The shell represented at Eig. 83 is the type of M. 

 Deshayes, T. approximata, and I had intended to adopt it. 

 I cannot, however, bring my mind to think that it is dis- 

 tinct from T. undulata, of which a more typical example 



is given at Eig. 84. 



Species 85. (Fig. a, b, Mus. Cuming.) 



Terebra strigilata. Ter. testa acieulari-subulatd, 

 livido-cinered vel lutescente, infra suturas fascia alba 

 purpiireo-puuctatd cingulatd, ad basin albifaseiatd, 

 anfractibus planatis, indicisis, loiigitudinaliter derive 

 plicatis ; aperturd pared, columella breviusculd, parum 

 contorta. 

 The combed Terebra. Shell acicularly subulate, livid- 

 ash or yellowish, encircled with a white purple-dotted 

 band below the sutures, white-banded at the base, 

 whorls flattened, undivided, longitudinally densely 

 plicated ; aperture small, columella rather short, but 

 little twisted. 

 Buccitmm strigilatum, Linnaeus, Syst. Nat. p. 1206. 

 Terebra strigilata, Lamarck. 

 Terebra Verreauxi, Deshayes. 

 Terebra MaUieroniana, Deshayes. 

 Terebra modesta, Deshayes. 

 Terebra acumen, Deshayes. 

 Terebra Argenvillei, Deshayes. 

 Terebra concinna, Deshayes. 

 Hab. Philippine Islands, Sandwich Islands, New Guinea. 

 A careful examination and comparison of the actual 

 types of the species quoted above as synonyms has satis- 

 lied me, without occasion of doubt, that they are all differ- 

 ent states, not very greatly varying, of the well-known 

 T. strigilata. 



Species 86. (Mus. Deshayes.) 



Terebra difficilis. Ter. testa elongato-turritd, carneo- 

 albd, anfractibus convexo-plauis, subangustis, densis- 

 sime coslellalis, sulco superne divisis ; aperturd parvd, 

 columella subcontorta. 

 The difficult Terebra. Shell elongately turreted, 

 flesh-white, whorls convexly flattened, rather narrow, 

 very densely finely ribbed, divided at the upper 

 part by a groove ; aperture small, columella slightly 

 twisted. 

 Deshayes, Pro. Zool. Soc. 1859, p. 304. 



Hab. - ■ ? 



A shell of solid growth, partaking somewhat of the cha- 

 racter of T. larvaformis, in which the fine ribs are so 

 crowded as almost to lap one upon the other. It comes 

 nearer even to T. Souleyeti. 



Species 87. (Mus. Deshayes.) 



Terebra subangulati. Ter. testa anguste subulatd, 

 flamda, anfractibus superne rude angulatis, sulco liue- 

 ari divisis, loiigitudinaliter coslatis, interstitiis elevato- 

 slriatis ; aperturd pared, subangustd, columella' sub- 

 contorta, basi recurvd. 

 The slightly angled Terebra. Shell narrowly su- 

 bulate, yellowish, whorls rudely angled round the 

 upper part, divided by a linear groove, longitudinally 

 ribbed, interstices elevately striated ; aperture small, 

 rather narrow, columella slightly twisted, recurved at 

 the base. 

 Deshayes, Pro. Zool. Soc. 1859, p. 300. 



Hab. - ? 



Described from a single specimen in M. Deshayes's col- 

 lection, not in a very good state, the shell being more or 

 less iucrusted with reddish matter.
