convex whorls. Whorls 6, lightly shouldered, base concave. 

 Suture impressed, undulate. Aperture elongately pyriform, pro- 

 duced into a comparatively long canal, which is subtruncate 

 and slightly deflexed to the right. Outer lip broken off. 

 Columella straight, obliquely truncate below, terminating in 

 a sharp point on reaching the left margin of the canal ; inner 

 lip forming a rather narrow callosity with a longitudinal furrow 

 parallel to the margin. 



Altitude, 6 mm. ; diameter, 3-5 mm. 



Type to be presented to the Colonial Museum. 



Three specimens only were dredged. This species is near 

 T. curtus, Murd., but may at once be distinguished from it by 

 the microscopic axial striation and the long canal.

Two immature empty shells. 



11. Siphonalia nodosa (Martyn). 

 Buccinum nodosum, Martyn, Univ. Conch., vol. i, 1784, fig. 5. 



Four examples, two of which were alive.

 1903, p. 374, pi. 38. 



Two live specimens, one of them about half-grown. The 

 larger specimen is decollated, has 7 whorls, and a length of 

 145 mm. Kesteven has published a paper on the anatomy of 

 Megalatractus — which, however, I have not seen yet — and has- 

 assigned the above species to this genus. This is a very in- 

 teresting addition to the New Zealand fauna. The protoconch 

 of this shell was figured in last year's Transactions (pi. 24,. 

 fig. 28).
