36 BRITISH SILURIAN BRACHIOPODA. 
as LZ. Lewisii, if that species had not been so rare in the Upper Ludlow: a fine large 
specimen, which we figure, was, however, found by Mr. Lightbody in the Upper Ludlow 
of Whitecliff, at Ludlow. In Ireland, Prof. M‘Coy mentions its occurrence in grey 
quartzites at Shanballymore, Oughterard, County Galway, and in shales at Ardaun, Cong ; 
but his example, of which I give a figure, is not so broad as we find to be the case in 
the generality of specimens; and as these are “ Llandovery” localities, its occurrence 
there is not likely. 
Prof. Phillips quotes the following localities in his ‘ Memoir on the Malvern Hills,’ &c. :— 
Malvern District, West of Rilbury, in the Aymestry limestone. Adderley District, 
Ankerdine Hill, Aymestry limestone; Hole Farm, Lower Ludlow. MWoolhope District, 
South of Putley, Aymestry limestone; Shucknall Hill, Aymestry limestone; Ecknall 
Copse; Bodenham, Aymestry limestone. Usk District, Usk; Cilfigan (Wenlock beds) ; 
Tucking Mill (Wenlock beds). Llandeilo District, Cilmaen Llywd (Ludlow rocks). 
Freshwater District, Freshwater Kast (Ludlow rocks).

Spec. Char. Somewhat pentahedral in outline, longer than wide; the sides nearly 
straight and parallel, rounded into the straight front; slopes forming the acuminate beak 
nearly straight and uniting at an angle of about 120°; valves very slightly convex, flattened 
along the middle; surface marked by numerous regular equidistant rows of concentric 
prominent ridges, which are wider or larger towards the middle of the shell; these ridges 
are also crossed by another set of radiating longitudinal striz, more closely disposed 
than are the concentric wrinkles, and producing by their intersection a granulose or reticu- 
lated appearance. 
Length of a large specimen 12, width 8 lines. 
Oés. Prof. Phillips gives us an excellent description and figure of the exterior of one 
of the valves of his species; unfortunately the interior is unknown. He observes that 
“the transverse striations are formed in sets, being extremely regular and at equal dis- 
tances for many rows, and afterwards equally regular but at smaller distances apart” 
(but this applies especially to the specimen described; in other examples the transverse 
striation gradually diminishes from about the middle of shell to the posterior and ante- 
rior margins). ‘‘ The surface appears granulated. The reticulation is less evident on the 
sides and on young individuals. In young specimens the outline is less characteristically 
marked, being in fact ovato-acuminate. (In other Lingulz, as in this, the lateral expan- 
sions near the beak increase and become characteristic with age.) The shell is always very
