Mr. E. A. Smith on new Species of Terebridse. 265 



which is angled in the middle and furnished with small sub- 

 acute nodules, is divided off by a most well-defined deeply cut 

 furrow, as in Ti trochlea, Desh. The ribs which form the rest 

 of the whorls are strong, contiguous, very regular, and acute. 

 The general colour is a pale livid fawn, the sharp edges or 

 angles of the ribs being whitish, and the basal half of the body- 

 whorl of a deej) cream-colour or very pale brown. 



Terebra concolor. 



T. testa polita, nitente, aut alba aut dilutissime caeruleo-alba, subu- 

 lata, subturrita ; anfr. planiusculi, sulco bene definito inajqualitcr 

 divisi ; pars superior nodulis parvis, elongatis, obliquis munita ; 

 pars inferior costis parvulis, subdistantibus, erectis (in anfr. ultimo 

 breviusculo 14-15 ad basim sensim obsoletis) instructa ; columella 

 carta, subrecta ; canalis brevLssimus. 



Long. 22 mill., diam. 6 ; apertura long. 5 mill., diam. 2^. 



Hob. ? 



A whitish shining species, furnished with oblique oblong 

 nodules on the infrasutural belt ; and on the remainder of the 

 whorls there are small, regular, upright ribs somewhat distant 

 from each other, which gradually become stouter towards the 

 apex. 



Terebra similis. 



T. testa subulata, polita, alba, subturrita ; anfr. primi 8-9 angulatim 

 convexi, cseteri planiusculi, sulco profuudo inaequaliter divisi ; pars 

 superior nodulis parvis erectis, subacutis, munita ; pars inferior 

 costis subvaHdis, erectis (in anfr. ultimo subelongato 14-15 fere 

 ad basim continuis) instructa ; apertura oblongo-elongata ; colu- 

 mella subrecta, elougata ; canalis brevis. 



Long. 22 mill., diam. 6 ; apertura long. 6^ mill., diam. 2^. 



Hah. ? 



At first sight this species is rather like T. concolor ; how- 

 ever, on closer comparison, there are found to exist several 

 good specific differences. In T. similis the infrasutural band 

 is defined by a deeper furrow than in T. concolor ; and the 

 nodules in the former are upright and rather acute, especially 

 those in the first seven or eight whorls, while those of the latter 

 are oblique, not so strong, and not acute. The longitudinal 

 ribs also of T. similis are considerably stouter than those in 

 T. concolor ; and the aperture and body- whorl of the latter are 

 likewise much shorter than in the former. 



Terebra japonica. 



T. testa subulata; anfr. 17, planiusculi, albidi, inferne zona lata oli- 

 vaceo-fusca (inter costas prsecipue conspicua) ornati, costis longi-
