Archey. — A Species of Daphnia new to New Zealand.

Jules Richard* included D. carinata King in his " Revision des Clado- 

 ceres," and remarked that Sars had " observed this species, of which he is 

 about to publish a description." Sars, in his paper of 1894, referred to in 

 the beginning of this paper, noted a cer- 

 tain similarity in appearance between D. 

 thomsoni and D. carinata. He says, " The 

 species (D. thomsoni) is very nearly allied 

 to D. carinata King, of which I have 

 had specimens for examination, differing 

 somewhat, however, in the form of the 

 rostrum and in the structure of the tail. 

 The carina of the head is, moreover, far 

 from being so strongly developed as in 

 that species, and the spine of the cara- 

 pace is also less elongated, sometimes 

 even very short." 



The specimens of D. carinata found 

 at Middleton and at Oamaru, in New 

 Zealand, are characterized by the expan- 

 sion of the anterior half of the carapace 

 into a large circular carina which sur- 

 mounts the head and anterior portion Oi 

 the body, ending under the head in a 

 distinct rostrum. On the posterior sur- 

 face of the rostrum, a short distance 

 above its point, is a small angular de-

pression to the level of which the very small antennules project. The 

 posterior spine of the carapace is slightly less than one-half of the length 

 of the carapace proper. The dorsal portion of the abdomen is provided 

 with four median dorsal processes, the anterior two of which are somewhat 

 longer and narrower than the posterior two, which are more rounded and 

 setose. 



This species has, up to the present, been recorded only from Middleton, 

 near Christchurch, and from Oamaru. 



Art. XXI. — Diptera of the Kermadec Islands. 

 By David Miller. 



[Read before the Otago Institute, 7th October, 1913.] 



Some time ago a collection of Diptera from the Kermadec Islands was sent 

 to me for identification by Dr. Hilgendorf, of Lincoln College. These 

 flies were collected on Sunday Island by Mr. W. L. Wallace, a member 

 of Mr. R. B. Oliver's expedition to the Kermadecs during 1908. A number 

 are common to the Kermadec Islands, Australia, and New Zealand, but 

 there are no types of the last country among the collection. 



Unfortunately, the greater part of this collection is seriously damaged, 

 so that the following brief list is all that can be drawn up.
