Species 12. (Fig. b, c, Mus. Cuming ; 

 Fig. d, e, Mus. Desliayes.) 



Terebra variegata. Iii describing this species at 

 Plate IV. I have remarked on the variable character of 

 its growth, and quoted as synonyms as many as seven 

 other species of different, authors. I now give figures 

 of four of the most striking forms. Fig. 12 4 represents 

 a variety from the mouth of the Gambia, West Africa, 

 named intertincta by Mr. Hinds and marginata by M. 

 Desliayes ; and the shell Fig. 12 c is a lighter variety of 

 the same form from the same locality. These pass by al- 

 most insensible gradations into the noduled variety of T. 

 armillata,T?ig. 72 b, which is a native of Panama, and are 

 scarcely distinguishable from a variety inhabiting California, 

 named by Mr. Carpenter Myurella alboclncta. 



The varieties of T. variegata, represented at Fig. 12 d 

 and 12 e, from the collection of M. Desliayes, illustrate 

 the form of this species which has the nearest relationship 

 with T. aspe.ra, and are identical with specimens marked 

 by Mr. Hinds in Mr. Cuming's collection " T. aspera, 

 var.," collected by him at Monte Christi, West Columbia. 



Species 71. (Mus. Cuming.) 



Terebra pulchella. Ter. testa subulato-turritd, fia- 

 vescente-spadiced, ferrugineo sparsim tinctd, basi albo 

 cinctd, anfractibus concaro-planatis, longitudinaliter 

 arcuatim tenuiplicatis, sulco superne divisis, sulco 

 ntroque latere crenato, margine prominente, tumido ; 

 aperturd oblongd, columella snbrectd, ad basin paulu- 

 luni recurvo. 



The pretty Terebra. Shell subulately turreted, yel- 

 lowish-fawn, sparingly stained with rust, base banded 

 with white, whorls concavely flattened longitudinally 

 arcuately finely plicated, divided at the upper part by 



a groove, crenated on each side of the groove, mar- 

 gin prominent, swollen ; aperture oblong, columella 

 nearly straight, a little recurved at the base. 



Deshayes, Joum. de Conch. 1857. 



llab. China Seas. 



The whorls of this species are peculiarly concave and 



arcuately plaited, and the margin, which is divided off by 



the encircling groove, has a swollen appearance. 



Species 72. (Fig. a, Mus. Deshayes; 

 Fig. b, Mus. Cuming.) 



Terebra armillata. Ter. testa subulato-turritd, fusca 

 ant lividd, ferrugineo et albo obscure fascial d et macu- 

 latd, anfractibus declivi-concavis, longitudinaliter irre- 

 gulariter plicatis, spiraliter liralis el sulca/is, sulco 

 superne divisis, margine prominulo, interdum valide ob- 

 lique nodulalis ; aperturd oblongd, columella' contorto- 

 recurod. 

 The bracelet-encircled Terebra. Shell subulately 

 turreted, brown or livid, obscurely banded and spotted 

 with rust and white, whorls slopingly concave, lon- 

 gitudinally irregularly plicated, spirally ridged and 

 grooved, divided by a groove at the upper part, mar- 

 gin prominent, sometimes strongly obliquely noduled ; 

 aperture oblong, columella twistedly recurved.

Terebra albicostala, Adams and Reeve. 

 Hub. Panama and Galapagos Islands (in sandy mud, at 

 a depth of from five to twelve fathoms) ; Cuming. 

 It is somewhat doubtful whether this is not a variety 

 of T. variegata. The specimen from M. Deshayes' collec- 

 tion is identical with specimens collected by Mr. Cuming 

 at the Galapagos Islands. The strongly noduled dark 

 variety is from Panama.
