wHiTEAvEs] FOSSILS OF HAMILTON FORMATION OF ONTARIO. 367 



of Ontario in. the fifteenth chapter of the "Geology of Canada," contains 

 the names of Favosites Gothlandica, F. turhinata, F. polymorpha, F. 

 cervicornin and F. hemi.tpherica. New specific names have since been 

 proposed for three of these, and it is now apparent to the writer that the 

 F. Gothlandica, of this list is F. Billingsii, Rominger ; that the F. poly- 

 morpha is F. clausa, Rominger ; and the F. cervicornis, — -F. arbuactda, 

 Hall. 



R.EMERIA KAMOSA. (N. Sp.) 



Plate 48, figs. 4 and 5. 



Cor.iUum compound, in the few specimens which the writer has seen, 

 which appear to be terminal branchlets of ramose colonies, either club- 

 shaped and slightly compressed, or fan-shaped, strongly compressed and 

 somewhat lobate above, more or less branched, in all cases erect and 

 usually widening toward the summit. Corallites simple, short, tubular 

 and slightly expanding, but closely amalgamated at the sides, radiating 

 from an iuiaginary median axis, but appressed and very slightly divergent, 

 their apertures directed outward and upward, all, but a few terminal 

 ones, opening at the sides. Calyces deep, septa rudimentary, almost 

 obsolete, apparently represented by numerous minute isolated tubercles, 

 or possibly spine bases, with which their inner surface is strewn. Aper- 

 tures of the calyces variable in outline, but mostly subovate or almost 

 circular, the larger ones averaging from four to five millimetres in their 

 longer diameter. Mural pores rather large and irregtilarly disposed. 



Surface nearly smooth, but marked with a. few faint transverse strife 

 of growth, which are scarcely visible without the aid of a len.s. Where 

 portions of the surface were rubbed down t> show the internal structure, 

 there are indications of funnel-shaped diaphragms immediately below the 

 calyces. 



The writer has seen only four specimens of this species, all of which 

 are now in the Museum of the Survey. Two of these were collected by 

 Mr. Townsend and are labelled by him, Township of Bosanquet ; one was 

 found by Mr. Kernahan, at Thedford; and one by the Rev. Hector Currie, 

 at Stony Point, four miles east of Kettle Point, Lake Huron. It is 

 just possible that these specimens should be referred to Vermipora, Hall, 

 as redescribed by Pvominger on pages 68 and 69 of his Fossil Corals of 

 Michigan, but in Vermipora the transverse diaphragms or tabulie are 

 said to be flat. All four show the " intercalation of new tubes by lateral 

 gemmation," which is one of the characters of Rominger's V. Jasaicidata.
