PAPERS AND ABSTRACTS. 



1. Note on the Flora of Mount Egmont : a Correction. By L. 

 Cockayne, Ph.D., F.L.S. (Read before the I'liilosopliical Insti- 

 tute of Canterbury, oth October, 1910.) 



In my report on the botany of the Tongariro National Park, page '.i'2, 1 have 

 inadvertently stated that the flora of Mount Egmont is "richer" than that of 

 Tongariro-Ruapehu, though the statement is discounted by the redundant words 

 '■ and contains certain species absent on the volcanic mountains of the centre," 

 which, of course, it would of necessity do if " richer." 



In point of fact, the flora of Mount Egmont is poorer than that of the centi'al 

 volcanoes, so far as is known, my notes taken in January, 1906, together with the 

 species given in Cheeseman's " Manual " and elsewhere, showing a total of only 

 ninety-seven species of spermophytes and pteridophytes for the subalpine and 

 alpine belts, as against more than 26.'} for the subalpine and alpine volcanic plateau. 



On the other hand, the slopes of Mount Egmont above the forest-line possess 

 a distinctly richer vegetation, and it was evidently vegetation, and not flora, to 

 which the word "richer" was meant to apply. Therefore, to read correctly, the 

 word "vegetation" should be substituted for the word "it" after the* word 

 " but " on page 32, line 53. 



2. Additions to the Fish Fauna of New Zealand : No. II. By Edgar K. 

 Waite, F.L.S. , Cui-ator, Cauterbui'v Museum. (Read liefore the 

 Pliilosophical Institute of Canterbury, .')th October, 1910.) 



The whole of the fishes collected by me during the cruise of the " Nora 

 Niven," 1907, having now been examined, the following are believed to be new to 

 science or to the known fauna of New Zealand, as indicated. 



The first part of the report was published in the "Records of the Canterbury 

 Museum." vol. i, 1909, p. 131 et. seq.. and a first epitome of subsequent additions 

 appeared on pp. 2r> and 26 of the present publication. 



Iicxea gen. no v. 



Family Trk-hhiridne. Body moderately elongate, fusiform. Mouth large, 

 with a single row of dagger-like teeth in each jaw, three enormous fangs towards 

 the fi-ont of the upper jaw, and two smaliei' ones in the lower jaw; teeth on 

 the palatines, none on the tongue. Two contiguous dorsal fins ; two finlets above 

 and below; pectorals small and low; ventrals small, each witli four spines; 

 caudal forked ; peduncle without keel. Scales small and smooth. Lateral line 

 single anteriorly, but divides, and forms an upper and lower branch. 



This genus is near to Prnmrth'irhfhyx Gill, differing principally in the character 

 of the ventral fins and in the eimfiguration of the lateral line. It includes the 

 type below diagnosed, Tliyi.^ltc.f pii/i/iff/ioirh.< Bleeker. T. micro pit ■■< .McCoy, and 

 possibly T. ( Prompf/ilrhf/i i/<) hen(/aleii.<!.^ Alcock. 



Kexea fuicifera sp. nov. 



B., vii ; D., xviii, ii, 15, ii ; A., ii, 14, ii ; V., iv ; P., 14; C, 18 + 8. 



Length of head, 32: height of body, 4-1; and length of caudal, 6-9 in the 

 length. Diameter of eye 4-K. interoibital space 4-6 : and length of snout, 2-4 in 

 the head. 



The length of the maxillary is half that of the head, and it extends to the 

 anterior of the orbit ; it bears twenty acute, flattened, distantly set teeth ; the 

 vomer has three large dagger-like teeth; the palatine teeth are similai- to the 

 maxillary ones, but smaller. The lower jaw markedly projects, and its extremity 

 completes the anterior contour of the head ; two large teeth at the symphysis 

 remain without the upper jaw Avhen the mouth is closed.
