(like II. Ilalli)", and which bears a considerable resemblance to that spe- 

 cies externally, though its internal structure has since been found to be 

 quite different. 



South-east shore of Lake Winnipegosis, a few miles north of Point 

 Braljant, and west shore of the same lake, at a small point north-west of 

 Fox Point, J. B. Tyrrell, 1889 : one specimen from each of these locali- 

 ties. South-east shore of Dawson Bay, Lake Winnipegosis, at Whiteaves 

 Point (two specimens), and on a .small island two miles west of this point 

 (one specimen) ; J. B. Tyrrell, 1889. West side of Dawson Bay, at the 

 south end of Eowan Island, D. B. Dowling, 1889 : one specimen.

Lake Manitoba, at Monroe and Pentamerus Points, J. B. Tyrrell and 

 J. F. Whiteaves, 1888. Dawson Bay, Lake Winnipegosis ; on the south- 

 east side at Whiteaves Point ; on foui- small islands at the south and south- 

 east end of the bay ; also on the south-west side, about five miles south 

 of Salt Point, and on a small point east of Steep Rock River; J. B. 

 Tyrrell, 1889. A few specimens, which seem to be intennediate in their 

 characters between the typical F. GotJi/anrUni. ;xnd the var. li'dllmjuii, and 

 which can scarcely be distinguished from the F. IIaiiiiJtoni<r oi Hall, were 

 collected at each of the.se localities. 



Most of the specimens are well preserved portions of large colonies, but 

 one large and ncaiiy perfect example is a depressed expansion of irregular 

 form, which measures about eleven inches in length, seven inches and a 

 half in lireadth and five inches in height. In each specimen the corallites 

 are polygonal (not rounded polygonal) and most of them are nearly equal 

 in .size, their average diameter being aliout three millimetres. The septa 

 are represented by rather short, rounded and api)arently very fragile 

 spines, which are usually broken oil'. The mural pores are disposed in 

 one or two (rarely three) longitudinal rows cm each of the prismatic faces 

 of the corallites, and where there are two rows the pores are .sometimes 

 alternate and at others opposite. The tabuLe are complete, continuous 

 and rather regularly disposed, but they do not show the " marginal punc- 

 tiform depressions " which Dr. Rominger describes as one of the charac- 

 ters of F. liillingsii.
