392 ON THE MOLLirSOA OF THE ' CHALLENaER EXPEDITIOIT. 



6. Teophon scolopax, n. sp. 



St. 150. Peb. 2, 1874. Lat. 52° 4' S., long. 71° 22' E. Be- 

 tween Kerguelen and Heard Islands. 150 fms. Eock. Bot- 

 tom temperature 35°'2. 



Shell. — Thin, chalkily porcellaneous white, club-shaped, with a 

 low, scalar, small-pointed spire, high-shouldered, right-angled 

 whorls on which are some small prickles, a tumid body, and a 

 long, thin, straight snout. Sculpture. Longitudinals — the whorls 

 are crossed by feeble, procumbent, almost appressed lamellae, be- 

 tween which are a few rounded lines of growth. Spirals — near the 

 top of each whorl, but separated from the suture by a broad, roun- 

 ded, but hardly declining shoulder, is a rectangular keel ; below 

 this, and widely apart, there are on the body-whorl three feeble 

 rounded threads ; on these, as on the keel, the longitudinal lamellae 

 rise into small, blunt, vaulted scales. The whole surface of the shell 

 is covered with submicroscopie scratches. Colour porcellaneous 

 under a thin chalky surface. Apex small, but too much eroded for 

 description. Whorls 6 to 7 (?), roundly tabulated above, with a 

 subrectangular keel, below which they are cylindrical ; the last is 

 a little tumid, rounded and rapidly contracted on the base, which 

 is produced into a long, thin, straight snout. Suture almost rect- 

 angular. Mouth almost round above, and entirely without angles, 

 funnel-shaped below, where it is drawn out into the long narrow 

 canal. Outer lip sharp, thin, well arched, direct till near the 

 canal, where it is very patulous. Inner lip concave above, and 

 then quite straight to the point of the shell ; a very thin and 

 narrow glaze covers the body to the beginning of the canal. Oper- 

 culum small, thin, yellow, oval, with a terminal but slightly in- 

 tui-ued nucleus. H. 0-95. B. 0-42. Penultimate whorl, height 

 0-12. Mouth, height 07, breadth 0-2. 



I have named this species from some likeness it has to a "Wood- 

 cock's head. It resembles T. Goodridgii, Eorbes, but has the body 

 smaller and squarer, the base more contracted, the canal much 

 longer and finer, and the whorls are tabulated below the suture. 

 It is larger than T. septus, the snout is straighter, and the whole 

 ornamentation is different.
