268 Mr. E. A. Smith on new Species of TerebridjB. 



cancellati ; cingulum suturale ex nodulis elongatis obliquis con- 

 stans, puuctorum serie notatum ; anfr. iiltimus elongatus, sub- 

 ventricosus ; columella subrecta, Cauda biplicata. 

 Long. 20 iniU., diam. G ; apertura long. 6 mill., diam. 3. 



Hah. Malacca. 



There is no species in the family with which this one can 

 be compared as regards affinity. The beautiful cancellated 

 surface, formed by numerous longitudinal and a few spiral li- 

 rations, which form little bead-like nodules at the points of 

 intersection, the convexity of the whorls, the infrasutural belt 

 formed of oblong nodules, and the peculiarity of the few upper 

 whorls, which, being encircled by but one or two spiral ribs, 

 have an angular outline, are characters which at once define 

 this from all other species. 



Myurella contracta. 



M. testa parva, turrita, cinerea ; anfr. 12, planiusculi, costis longitu- 

 dinahbus validis, leviter arcuatis, obliquis (in anfr. ultimo 17-18 

 ad basim continuis) instructi, sulcis parvis, transversis, pluribus, 

 profundis costas inter et levibus costas supra, ornati, et infra 

 suturam punctorum serie inter costas inajqualiter divisi ; anfr, 

 ultimus basi contractus ; apertura parva, fusca ; columella obliqua, 

 labio callo crassiusculo fusco juncta. 



Long. 17 miU., diam. 3|. 



Hah. ? 



The strong ribs (made somewhat nodulous by being cut 

 across by the numerous transverse sulci, which are rather 

 deep in the interstices), the basal contraction of the last whorl 

 (which is broader at the suture than inferiorly), the small brown 

 aperture, and the callosity on the columella (which extends to 

 the junctui-e of the outer lip with the body-whorl) are the 

 chief distinguishing marks by which this peculiar shell may 

 be recognized. 



Myurella granulosa. 



M. testa subulata, brunnea, infra suturam zona angusta cinerea cincta ; 

 anfr. 14- ?, elongati, convexiusculi, costis obsoletis nodulosis (su- 

 perne praecipue) longitudinalibus subpallidis (in anfr. ultimo 13) 

 instructi, lirisque spirahbus 4-5 obsoletis, costarum nodulos con- 

 nectentibus (infima suturae contigua), cincti ; anfr. ultimus elon- 

 gatus, subventricosus ; columella subrecta. 



Long. 26 miU., diam. 6. 



Hah. Japan [A. Adams). 



This is a very peculiar species, quite distinct from any other 

 belonging to the family. It is chiefly characterized by the in-
