almost tlic same. The teeth of the raduLa (Figs. XVI, XYII), how- 

 ever, are very different. The rhachidian tooth is very slender, with 

 a small irregidarly-shaped cusp, bearing a single blunt denticle, 

 usually on the left side, whilst the lateral teeth have a long and stout 

 inner denticle and three, smaller, outer ones. 



I have much pleasure in associating with this species the name of 

 its discoverer. Dr. Arthiir Dendy, Professor of Biology in the Canter- 

 bury College, University of Xew Zealand.

Like Janella, but the eye-peduncles short and conical (Hutton). 

 Back of body smooth, or faintly granulose. In spirit specimens the 

 lateral grooves on the foot are present, but not very conspicuous, and 

 there is no thread-like line between groove and sole. Mantle-area 

 distinct, triangular, sometimes quadrangular. The median dorsal 

 groove not always extending to the head. Keual opening a short 

 distance in front of the mantle-area. Anus below the pulmonary 

 orifice, near the foot margin,

A full description of this species and its anatomy has been given by 

 Captain Hutton. The rhachidian tooth of the radula is very distinct, 

 somewhat approaching that of A. papiUatus in the emarginato anterior 

 end, but there is no central denticle. The situation of the renal 

 opening in front of the mantle- area is not met with in any other species, 

 and is correctly reproduced in the figure given by Captain Hutton.' 



This species attains a rather large size. The dorsal grooves in spirit 

 specimens are sometimes very indistinct, and the back quite smooth. 



The dimensions of a rather small specimen are : — 



1. Length over back from head to tip of tail, 55 mm. 



2. Length of sole, 45 mm. 



3. Width of back, 21 mm. 



4. Breadth of sole, 8 mm. 



5. Breadth of groove between sole and back, 3 mm. 



6. Distance of anus from right tentacle, 8 mm. 



7. Distance of anus from pulmonary orifice, 9 mm. 



8. Distance of anus from foot margin, 2*5 mm. 



9. Distance of pulmonary orifice from head, 16 mm. 



The genital orifice is close behind the right tentacle.
