﻿I02 "ENDEAVOUR" SCIENTIFIC RESULTS. 



Danilia telebathia, sp. nov. 

 (Plate xviii., figs. i6, 17.) 

 Shell ovate, acuminate, imperforate, thin and slightly 

 nacreous. Whorls seven, the first wound horizontally, thus 

 giving the spire a decapitated aspect. Median whorls 

 separated by a channeled suture, flattened on the shoulder and 

 subangled at the periphery, the last slightly descending 

 behind the aperture. Colour : Pale buff with scattered irregular 

 dashes of ochre alternate chocolate dots on the outer lip. 

 Sculpture : The last whorl carries eleven widely-spaced fine 

 spiral cords, the peripheral strongest. Of these six appear on 

 the penultimate and fade gradually away on the upper whorls. 

 Both cords and interspaces are crossed by delicate oblique 

 lamellae which rise into scales upon the cords. They are 

 crowded on the last whorl, do not cross the suture from 

 whorl to whorl, and become fewer and fainter ascending the 

 spire. The initial whorl is smooth. Aperture very oblique, 

 subcircular. Outer lip effuse, fimbriated by the termination of 

 the spiral sculpture, inner lip projecting over the umbilical 

 region, thence spread from the axis to the right insertion as 

 a solid sheet. Columella spirally ascending within, terminat- 

 ing below in a downwardly directed tubercle, succeeded by a 

 deep notch and an answering ridge. Thence along the edge 

 of the gullet underneath the external varix are about a score 

 of callus rays, alternately long and short, leading to the 

 throat. Behind the aperture, about a millemetre from the 

 free edge, is a sharp, narrow varix rising gradually at the base 

 and ending abruptly at the suture. Length 10, breadth 8 mm. 

 judging from literature, our shell is more elevated and finely 



sculptured than D. tinei, Calcara. 



This genus has not before been reported from the Southern 



Hemisphere. As in the Mediterranean and off the Azores, it 



appears to be confined to deep water. 



While on the subject of deep-sea Trochoids, I take this 



opportunity of pointing out that Trochus (Gihhula) glyptus, 



Watson,! from 410 fathoms off Sydney, should be transferred 



to Turcicula. 



Hah. — Several specimens from 100 fathoms forty miles 



south of Cape Wiles, South Australia. 



Leptothvra fugitiva, sp. nov. 



(Plate xviii., figs. 18, 19, jo.) 



Shell small, solid, depressed-turbinate, narrowly perforate. 



Colour white. Whorls three and a half, rapidly increasing, 



last rounded, descending at the aperture. Spire slightly
