NorsEs on AND DESCRIPTIONS OF THE SPECIES. 
1. Linevta Lesvzvri (Rouault). Pl. LV. fig. 1. 
Bull. Soc. Géol. de France, vol. vu. 2nd ser. p. 727, 1850; Salter, 
Quart. Journ. Geol. Soc. vol. xx. p. 292, pl. xvii. fig. 1; Day. 
Sil. Mon. p. 42, pl. 1. figs. 1-11. 
This curious species has been correctly described and illustrated 
by Mr. Salter and myself. I, however, much regret that M. Rouault 
did not figure his French type. It varies considerably in its compara- 
tive length, so that the sides, instead of being always subparallel, 
sometimes diverge at once from the beak to the frontal margin; and it 
might, under that aspect, be readily mistaken for a distinct species. 
L. Lesueuri was found im situ by M. Rouault in the Lower Silurian 
(Lower Llandeilo), at Guichen, in Brittany, and by MM. E. de Ver- 
neuil and Triger at St. Léonard, in the Department of the Sarthe. 
It is not very rare at Budleigh-Salterton, and was once found by 
Mr. Vicary associated with Rhynch. Vicaryi. The Rev. P. B. Brodie 
mentions having picked it up, as well as Orthis redux, var. Bud- 
leighensis (but separately), in quartzite or sandstone pebbles similar 
to those discovered by Mr. Vicary, in the drift at Rowington, in War- 
wickshire. The shell which approaches most to LZ. Lesueurt is the 
L. Bechet from the Upper Llandovery of Marloes Bay. 
2. Linevta Rovavtrti (Salter). Pl. IV. fig. 2. 
“Quart. Journ. Geol. Soc. vol. xx. p. 293, pl. xvii. figs. 4 & 5; 
Day. Sil. Mon. p. 40, pl. i. figs. 14-20. 
This is a very remarkable species, and has been described and 
illustrated by Mr. Salter and myself. I have seen French examples 
in the collection of M. E. de Verneuil which agree with ours, but 
the shell seems to have attained somewhat larger proportions in the 
«< Armorican Grit ” of Brittany. Certain specimens bear much resem- 
blance to Lingula erwmena, Phillips, with which it might sometimes 
be confounded. Z. Rouaulti is a Lower-Silurian species and not very 
rare at Budleigh-Salterton; but no other Brachiopod has hitherto been 
found associated with it in the same pebble.
