Formations and localities in England. Wenlock Limestone, Dudley ; Lincoln Hill, Bent- 

 hall Edge, Wenlock; Conygree Wood, Ledbury ; West flank of the Malverns j Winsloiv

A magnificent hemispherical specimen of this coral, fourteen inches in diameter, was found at 

 Haven near Aymestry in Wenlock Limestone, by the Rev. T. T. Lewis. 

 Foreign locality and authority, Eifel, Goldfuss. 

 Stromatopora nummulitisimilis, sp. n. Lons. PI. 15. f. 32, 32 a nat. size and magnified twice. 



S. Small, very flattened spheroids, similar to a nummulite in shape, and composed of many 

 thin concentric layers, formed around a nucleus, consisting generally of a joint of a crinoidal 

 remain. 



Formation and localities. Wenlock Limestone, Crews' Hill near Alfrick, Worcestershire ; 

 Mathon Lodge, Malvern ; and also at Lye near Aymestry 1 . 

 Alveolites, Lamarck. 



Alveolites ? fibrosa, sp. n. Lons. PI. 15. f. 1, 1 a nat. size. 



A. Encrusting ; layers concentric, thin, but of unequal thickness, tubes short, externally an- 

 gular, internally round. No connecting foramina detected : surface of the tubes in each layer 

 slightly concave. 



It is not without hesitation that this fossil is placed in the genus Alveolites. The speci- 

 mens first examined, presented only one layer of tubes ranging the whole thickness of the coral 

 (f. 1 a), and they were believed to be a variety of Favosites fibrosa. (See ante, p. 612, Turbo 

 Cor allii.) The beautiful specimen in PI. 15. f. 1, was afterwards added to the collection : and from 

 regularity in the surface of each layer, I have been induced to remove the coral into the genus 

 Alveolites. On examining several specimens of the different species of Favosites, so great a 

 diversity was found in the range of the transverse divisions within the tubes, that no fracture 

 could give the level uniformity of surface presented by the fossil here called Alveolites fibrosa. 

 Formations and localities. Upper Ludlow Rock and Aymestry Limestone, Larden, 

 Churn Bank, or Palmer's Cairn near Ludlow. 

 Favosites, Lamarck. 



Favosites alveolaris (De Blainville), PL 15 bis. f. 1, 1 a, 1 b, 2, 2 a. — 1 segment of a hemispherical 

 mass, nat. size, 1 a portion magnified twice, 1 b exhibits the internal lamellae, 2 is from a larger 

 variety, nat. size. The pores are well displayed upon the angles of this specimen, but near 

 the base of one of the tubes are four pores on the surface of the plane. 



The distinguishing specific character consists in the connecting foramina being on the angles 

 of the tubes.

1 A mass eight inches long, seven broad and two thick, consisting almost entirely of this small coral, was 

 found by the Rev. T. T. Lewis and myself at Crews' Hill, north of the Malvern Hills; and to the zeal of my 

 friend in carrying this specimen when added to a well-loaded bag, the preservation of the mass entire is due. 

 Mr. Lewis has since found the species in the Wenlock Formation near Mathon Lodge, Malvern. — R. I. M.
