560 REPORT—1885. 
diagnoses occupy about twenty-six pages, two and a half of which 
number are devoted to the geographical and bathymetrical range of 
species. This part of the Report, however, will appear in its proper 
place further on. 
In justice to Mr. Hincks and to Mr. A. W. Waters, after the very full 
remarks on the species by Mr. Busk, it would appear to me very unwise 
to pass over the labours of these respected authors. 
Notes on the genus Retepora, with descriptions of new species. By 
the Rey. Thomas Hincks, ‘ Ann. Mag. Nat. Hist.’ May 1878. 
Mr. Hincks begins this paper by giving a list of previously described 
species from different seas by different authors. From Australia five 
species ; from the South seas, one ; from India, one; from Florida, three; — 
from the Arctic and North seas, two; and from the British and Medi- 
terranean seas, two: after which he proceeds with a very full description 
of new or little known species. 
Genus Retepora, Lamarck. 
a, With an oral fissure. 
1. Retepora Couchii, Hincks (op. cit. p. 355, pl. xviii. figs. 1-6) | 
= Retepora Beaniana, Hincks, ‘ Dev. and Cornwall Cat.’ — 
ra - cellulosa, var. Beaniana, Manzoni. 
2. a pretenuis, Hincks (op. cit. p. 356, pl. xix. figs. 6, 8). 
2. Without an oral fissure. $ 
plana, Hincks (op. cit. p. 358, pl. xviii. figs. 7,8). 
tessellata, Hincks ( op. cit. p. 358, pl. xix. figs. 9-12). 
robusta, Hincks (op. cit. p. 359, pl. xviii. figs. 9-10). 
ee 
Mr. Hincks says that the following species have already been de- 
scribed,' but he ventures to give a fuller diagnosis :— 
6. Retepora monilifera, Macgil. (Hincks, op. cit. p. 360, pl. xix. figs 
1-5). 
(f Phoenicea, Busk, ‘Cat. Mar. Pol.’ 
8. 5 granulata, Macgil. (Hincks, op. cit. p. 363, pl. xix. figs 
13-15). 
9 cellulosa, Smitt (Hincks, op. cit. p. 364). 
Family XIX. Cribrilinide, Hincks. 
‘Brit. Mar. Pol.’ vol. i. p. 182; ‘ Chal. Rep.’ p. 130. 
Mr. Hincks’s description of this family group is as follows :— 
‘Zoarium adnate, forming an indefinite crust, or erect. Zocecia 
having the front wall more or less fissured, or traversed by radiating 
furrows.’ Mr. Busk, however, adds to his description other characters, 
and slightly modifies the remarks of Mr. Hincks :— 
‘Zoarium crustaceous, or adnate (lepralian), or erect and unilaminar 
(hemischaran). Zocecia, front’ with transverse or radiating fissures or 
rows of punctures without fissures. Mouth simple, sub-orbicular, some-— 
times mucronate or semicircular; with or without a median sub-oral 
pore.’—Chal. Rep. p. 130. _
