ON RECENT FOLYZOA. 561 
Genus 60. Cribrilina, Gray. 
Cribrilina, Gray, Hincks, Smitt, Busk, ‘Chal. Rep.’ 
Lepralia (pars), Busk, ‘ Brit. Mus. Cat.’ Johnsé. 
Reptescharella, D’ Orbigny, ‘ Pal. Franc. Tert. Cret.’ 
_ Escharipora, Smitt, 1867. 
_ ‘Front of cells fissured, or simply punctured in regular or transverse 
rows.’—Busk, ‘ Chal. Rep.’ 
Tn the ‘British Marine Polyzoa’ Mr. Hincks describes the following 
es. Hxcept in some few instances I have not thought it wise to 
teproduce the whole of the synonyms given by authors, as a very full 
was appended to a previous list in the Fifth Report on Fossil 
zoa, ‘ Brit. Assoc. Rep.’ and is furnished (from Busk and Hincks) in 
ntroductory part of the present Report. 
__ L. Cribrilina radiata Moll. (op. cit. pl. xxv. 1-9). 
Var. a, Antrim, deep water. 
Var. B, (op. cit. pl. xxv. fig. 4). 
Var. y, tenuirostris, Madeira. 
* punctata, Hassall (op. cit. pl. xxvi. figs, 1-4; pl. xxiv. 
fig. 3). 
Var. a, with a central umbo. 
a annulata, Fabric. (op. cit. pl. xxv. figs. 11, 12). 
- figularis, Johnst. (op. cit. pl. xxvi. figs, 5-7). 
Var. a, fissa. 
ie Gattye, Busk (op. cit. pl. xxv. fig. 10). 
Var. a, Hastings, Miss EB. C. Jelly. 
Many of these species have a wide geographical range both around 
our coast, some of them reaching far north. The varieties are very local, 
_ Only one genus—Cribrilina—is at present admitted by Mr. Busk in 
assified list, but in the classification of Mr. Hincks another genus, 
miporella, Smitt, forms part of Cribrilinide, Hincks. In the 
einition, however, of Mr. Busk, the hemischaran forms of Mr. Hincks 
included. 
the ‘Challenger Report’ the following species are described in 
everal sections by Mr. Busk. 
. 3 $a, Front fissured. §$1. Adnate (lepralian). 
1 Cribrilina radiata, Moli., ‘Chal. Rep.’ p. 131. Found only in two 
_ . stations, 75 and 135 A. 
» latimarginata, Busk, ‘ Chal. Rep.’ pl. xxii. fig. 10. One 
station only 320 on dead coral. In his remarks Mr: 
Busk says that Reuss describes and figures in his 
‘Paleon. Stud.,’ under the name of Celleporaria radi- 
ata, a form in so many respects closely resemblin g his C. 
latimarginata. In other respects there is a difference. 
§§ 2. Free, erect or decumbent (hemischaran). 
8. Cribrilina philomela, Busk, ‘ Chal. Rep.’ pl. xvii. fig. 6 
= (?) C. speciosa, Hincks, * Aun. Mag. Nat. Hist.’ 1881 
= (?) Reptescharella inequalis, D’Orb. 
Var. a, adnata, Busk, ‘Chal. Rep.’ pl. xxii. fig. 7. 
(?) C. figularis, var. Hincks.
