This species has no spiral sculpture. The longitudinal ribs 



are tliicker at the top ; and being cut across bj the narrow 



transverse furrow a little below the suture, the appearance of 



a narrow infrasutural belt is thus produced. 



Terehra [MT/urella] fuscocincta, sp. nov. 



Testa parva, subulata, nitens, albida vel cornea, lineis dnabus fuscis 

 cincta, altera satnratiore paululum infra suturam, altera fere ad 

 anfractuum basim ; anfract. ultimi basis fusca ; anfr. lU, eonvexi- 

 usculi, infra suturam leviter constricti, costis validis, acutis, 

 arcuatis, supcrne subtubercularibus (in anfr. ultimo circiter 10 

 vix ad basim attenuantibus) iiistructi ; columella brevis ; cauda 

 lira distincta cincta ; canalis brevis, latus.

Var. anfr. planiusculis, costis rectis munitis.

This species is coloured somewhat like inimilio.^ but is at 

 once distinguished from that form bj the absence of the trans- 

 verse striation and by the existence of fewer ribs. The upper 

 brown line or band is quite at the top of the whorls mpumilio, 

 whereas in the present species it is a little below the suture, 

 colouring a slight depression or constriction which exists there. 



The variety is allied to tenera, Hinds, which, however, is 

 shorter, has fewer ribs, and wants the brown line near the 

 base of the whorls and that around the periphery. 



Terehra [Myurella) MacAndrewii, sp. nov. 



Testa parva, breviter subulata, parum nitida, albida, zonis duabus

 cincta ; anfract. 11, convexiusculi, superne leviter constricti ; costis 

 longitudinalibus parvis superne impressione spiral! levi divisis 

 (in anfr. ultimo 12-13 basi scnsim attenuatis) instructi, et striis 

 gracdlimis, creberrimis, spiralibus ornati ; anfr. ultimus zona 

 tertia fuscescente infra peripheriam cinctus ; columella brevis, pur- 

 purascens ; labrum aliquanto exj^ansum ; canalis perbrevis, latus.
