L. asperelliis (3020) is most nearly allied to this species, which, however, 

 dift'ei's therefrom in its narrower outline and by the absence of metallic 

 red reflections. The sculpture of the thorax is not so coarse, but that of 

 the elytra is just the reverse, nearly approaching that of L.. foveigerus.

Subelongate, slightly convex, shining : castaneo-rufous, legs and an- 

 tennae paler, sparingly clothed with slender yellow hairs. 



Head smooth on the middle, finely punctate elsewhere. Thorax rather 

 broader than long, its sides finely margined, not quite straight, being 

 slightly rounded at the middle, with rectangular posterior angles ; the apex 

 broadly medially rounded and deeply emarginate towards the obtuse 

 angles : its surface finely and distantly punctured, but quite smooth along 

 the middle, and nearly so on an elongate space between that part and 

 each side. Scutellum flat and smooth. Elytra quite as wide as thorax at 

 the base, gradually narrowed backwards, with many somewhat irregular 

 series of very fine punctures. 



Underside rufous, with pubescence like that of the upper surface, the 

 prosternum coarsely punctured, the metasternum and abdomen finely. 



On comparing this with one of C. ferrugata (31-56) collected by Mr. Helms 

 at Greymoutli. and kindly purchased for me at London by Mr. George 

 Lewis, F.L.S., I find that this species differs in being more distinctly clothed 

 and more finely sculptured. The thorax is not of the same shape, and the 

 eyes are decidedly more convex.

Art. XVII. — Some Notes on Rotifera not previously recorded as occurring 



in New Zealand. 



By C. Barham Morris, F.R.M.S. 



[Read before the Otago Institute, Id October, 1912.] 



This paper deals with twenty-two species of Rotifera which have not so 

 far been reported as having been found in the Dominion. It is the result 

 of four years' pretty constant searching of between two and three hundred 

 ponds and creeks, chiefly in North Otago, by myself and half a dozen other 

 willing helpers. During the course of this period I have mounted some two 

 thousand slides of pond-life, adopthig Mr. Rousselet's formalin method in 

 the majority of cases, and alwa)^s with the best results so far as the pre- 

 servation 'of the specimens was concerned ; and my slides of Rotifera 

 mounted four years ago are as good to-day as they were when first rung. 

 I have, of course, come across many other species, such as Floscularia 

 ornata, Melicerta ringens, Rotifer vulgaris, Hydatina senta, &c., round about 

 Oamaru, but as these have already been recorded in the Trans. N.Z. Inst. 

 I have not referred to them.
