In T. stramtnea the prcsiitural band and the cord following it are 

 obliquely costulate, the presutural band flattened. Otherwise it is 

 much like the present species. T. funiculata Hinds is more closely 

 related. It is decidedly more slender than T. langfordi, with more 

 spiral threads, one at the periphery more prominent. 



A form of which I found a single specimen on the dredger dump 

 at Honolulu is much more slender. The groove di\iding the sutural 

 band is deeper, and there are but three spiral cords below the one 

 accompanying the band. In the small number of spirals it differs 

 from T. jumcidata. This form may be called T. langjordi angustior 

 (PL XII, fig. 6.) 



Length 29, diameter 5, aperture 4.5 mm.; 20 whorls remaining. 



I at first thought this form was T. sculptus Pease, but that is 

 described as having a conspicuous nodose rib. 



The spiral sculpture is much more pronounced than in T. laevi- 

 gata Gray. 



Terebra argus brachygyra n. siibsp. PI. XII, fig. 4. 



The shell is smaller than T. argus with shorter^ less oblique whorls; 

 the sculpture of low ribs cut by an irregularly punctured spiral sul- 

 cus is stronger, and visible down to the penult or even on the last 

 whorl. The pattern of three series of squarish pale buff spots on an 

 almost white ground is very indistinct. 



Length 40, diameter 8 mm., 12 whorls remaining, the apex 

 broken. 



Length 39, diameter 8.7 mm.. 12 whorls remaining. 



Off Honolulu, 3 to 8 fms. D. Thaanum. 



Terebra peasei Desh. 



This species of the section Stnoterehrum has been considered a 

 synonym of T. pundiculata by Ilee\e. Pease (Amer. Journ. Conch. 

 V, p. 64) concurs in this synonymy. The locality of T. puncticu- 

 lata was unknown. The description agrees well with the Hawaiian 

 species except for the phrase "pHcis regularibiis, depressis. latis, 

 ohtusis" and the statement that the whorls are " subaequaliter 

 divisis" by the presutural line. 



In the Hawaiian shell the folds could not be called wide, and the 

 division of the whorls is well above the middle, 



Reeve's figure of T. puncticulata evidently represents the type of 

 T. peasei, agreeing \vith that, and not with puncticulata^ in measure- 

 ments.
