Vol. 67.] FROM THE PARADOXIDES BEDS OF COMLEY. 301 



1876. Cf. IAngulella (?) sp. indet., Linnarsson, ' Brachiopoda of the Para- 

 u doxides Beds of Sweden ' BihangK. Svensk. Vetensk.-Akad. Handl. vol. iii, 



No. 12, p. 15 & pi. iii, figs. 27-28._ 

 1883. Cf. IAngulella ferruginea Davidson, 'Monogr. Brit. Foss. Brach.' (Pal. 



Soc.) vol. v, pi. xvii, fig. 35. 



Shell corneous, small, slightly convex, ovate ; widest about a 

 third from the front, length about one and a half times the breadth ; 

 broadly rounded in front ; sides tapering to the beak, which in the 

 pedicle-valve appears to have been acutely pointed. Numerous 

 concentric growth-lines. Pedicle-slit narrow. 



Dimensions. — Length = 4 millimetres, breadth = 2 to 2| mm. 



Locality and horizon. — The upper section on the Sboot- 

 Tlough Road, Comley ; from a band of the Shoot-Rough-Road 

 Flags with Paradoxides davidis, and also from a band with. Para- 

 doxides rugulosus at the top of the Shoot-Rough-Road Sandstone. 



Note. — Three examples of this small Lingulella have been 

 collected, and they agree fairly well with the Afenevian species from 

 St. David's, although the Shropshire form seems to be rather more 

 acuminate at the beak. The Lingulella (?) figured by Linnarsson 

 from the Paradoxides-forcJihammeri strata of Sweden may be 

 identical. 



Lingulella (?) spp. indet. (PI. XXVI, figs. 7-8 6.) 



An imperfect single valve (fig. 7) has been obtained, which differs 

 from the small Lingulella described above. It was found in tb^ 

 lower section on the Shoot-Rough Road, Comley, in the band oi 

 the Shoot-Rough- Road Flags yielding Billingsella lindstrcemi, var. 

 salopiensis. The valve is nearly flat, the sides taper rapidly 

 towards the beak, which is not preserved but appears to have been 

 acuminate. The front is not preserved. Along the sides is a 

 raised flat border or flange, about 05 millimetre wide. The shell- 

 substance consists of several layers. The surface-ornamentation 

 is not preserved, and the inner layers are smooth, except for faint 

 indications of longitudinal striae on one of them. Muscular mark- 

 ings not shown. Length = 10 millimetres or more ; width=6 mm. 

 I Another form (figs. 8 a & 8 6), about 3 mm. long, rather broad, 

 almost subpentagonal in outline, and possessing a concentrically 

 striate exterior, occurs in the Shoot-Rough-Road Flags of the 

 upper section, in association with Acrotreta aff. socialis. In shape 

 it resembles, but is much smaller than, Linnarsson's Lingulella (1 ) 

 naihorsti of the Olenellus-kjendfi Zone at Andrarum in Scania. 1 

 i - Another undetermined lingulelloid shell, a small oval form, occurs 

 with Lingulella cf. ferruginea in the Paradoxides-rugulosus band of 

 the Shoot-Rough-Road Sandstone of Excavation Xo. 23.
