No less than ten species of Favosites have been recognized as occurring in the Devonian 
Rocks of Canada, of which Favosites Gothlandica, F. basaltica (?) F. Forbesi, F. hemispherica, 
F. polymorpha, F. cervicornis, F. reticulata, and F. dubia are found in the same formation in 
Europe ; whilst 7’. turbinata and F. Chapmani are as yet not known elsewhere.

(Many more references could be given, but the above are the most important). 
The following is the diagnosis given by Mr. Billings of this cosmopolitan species in the 
paper already referred to :—‘ Corallum forming spheroidal, pyriform, or large hemispheric 
or flattened masses; corallites in general between one line and one and a half lines wide, 
sometimes less or more, often two lines; transverse diaphragms usually complete, rarely in- 
complete ; mural pores in one, two, or three series, usually two, those of the same series about 
half a line distant, sometimes less; pores surrounded by an elevated margin; faces of the 
tubes with one or two longitudinal strize, more or less distinctly developed ; radiating septa 
represented by a series of small spines, often in the rudimentary form of tubercles.” 
The chief characters which may be relied upon as distinguishing typical examples of 
Fawosites Gothlandica (Liam.), are the following :—1. The corallites are of comparatively large 
size, usually about one and a half lines in diameter, but varying from one to two lines. 2. 
The corallites are generally markedly polygonal, and are for the most part tolerably uniform 
in their dimensions. 3. The mural pores are in two rows, placed alternately or sometimes 
oppositely on the faces of the corallites, and surrounded by elevated margins. 4. The tabulee 
are complete, that is, extend from one side of the theca to the other. 5. Perfect examples 
are usually of a more or less hemispheric or pyriform shape, and have their lower surface 
enveloped in a thicker or thinner concentrically wrinkled epitheca. 
Whilst the above characters are generally found to co-exist in typical specimens of F. 
Gothlandica, there are, nevertheless, numerous departures from this state of things which 
must be attended to in studying this protean species :— 
The size of the corallites in some specimens not otherwise separable from F. Gothlandica 
is sometimes uniformly below the average in an entire colony, not exceeding one line, or even 
a little Jess than this. This might not seem an important difference, but, as noticed by 
Mr. Billings, it gives the coral an apparently very distinct general appearance. 
The corallites, though usually distinctly polygonal, are sometimes nearly round, through. 
out an entire colony; and their relative size in the same mass may vary to some extent. -
