Paleozoic Corals in the British Museum. 475 
Many Devonian Corals have been referred to the genus 
Chetetes, but in most cases these have been shown to belong 
to other genera. In concluding his notice of Chetetes Prof. 
H. A. Nicholson remarked, “The species. . . . are not known 
to occur out of the Carboniferous (and possibly the Devonian) 
rocks” (‘Tabulate Corals,’ 1879, p. 266). There are, 
however, a few forms which should be referred to in passing ; 
for instance, in 1851, Messrs. Edwards and Haime described 
their C. Trigert (Mon. Polyp. Foss. Terr. Pal. p. 269, 
t. xvil. fig. 6), which from the description appears to belong 
perhaps to the genus. Mr. A. Winchell has likewise described 
(Report Geol. & Industrial Resources of the Peninsula of 
Michigan, 1866, pp. 89, 90) two species under the names of 
C. hamiltonensis and C. microscopicus. In the first, the septa 
are said to be “ complete,” and we should therefore doubt its 
reference to the present genus at all; whilst the description 
of the second is, lacking a figure, too brief for identification. 
The Devonian rocks of Muscatine, Iowa, have yielded to 
the researches of Dr. C. A. White an exceedingly fine form, 
C. muscatinensis, White, of which we have examined 
specimens; and although in many respects resembling a 
Jheetetes, we do not feel justified in at once pronouncing it 
to belong to that genus. Lastly, Prof. F. von Rémer has 
recently described (Lethea Geogn. 1883, i. Th. p. 459) a 
coral from the Devonian rocks of the Hifel, as C. stromato- 
poroides. This is clearly distinct from our species, and, in 
fact, the author appears to doubt its reference to Chetetes 
at all. 
We have much pleasure in associating with this coral the 
name of the late Mr. W. Lonsdale, who may be said to have 
laid the foundation for the study of British Devonian Corals, 
and for that of the genus Chetetes in particular.
