BRONTEUS. 35 



containing a small lateral tubercle which represents the upper lobe. Basal furrow 

 sharply truncating the glabella, followed by a basal lobe consisting of a central 

 portion and two narrow, separated, lateral ridges. Neck-lobe high and arched. 

 Surface of the glabella bearing on the posterior parts rather fine tubercles running 

 into transverse lines, the tubercles disappearing in the front parts and the lines 

 becoming continous strias. 



Size. — The glabella is 19 mm. in length and 21 mm. in width. 



Locality. — There is a small specimen in my collection from Lummaton, and a 

 larger one in the Torquay Museum, which probably comes from the same place. 



Remarks. — The present species differs from B. delicatus in the great width of 

 its glabella, and the pits in the furrows that bound it, and from the other Devon- 

 shire species in the character of its ornamentation. 



In B. umbellifer, Beyr., 1 B. pustulatus, Barr., 2 B. oblongus, Corda, 3 and some 

 other Bohemian forms, the depressions on the glabella produce a T-shaped 

 appearance of its central parts. In B. Partschii, Barr., 4 there are no signs of 

 granulations, the depressions are more pit-like and the sides of the glabella more 

 concave.

Description. — Body large, flat, oval. Head short, wide, rounded. Border 

 almost straight in front, marked with a few fine transverse ridges chiefly seen 

 below, curving gently round the cheeks and sweeping round the angle. Glabella 

 triangular or shovel-shaped, hardly higher than the cheeks, highest and somewhat 

 pinched behind, sloping gradually to the border, with which it merges ; bounded 

 laterally by deep furrows, at first straight and then arching gently outwards, 

 separating it from the fixed cheeks, and containing two pits, distant one about one- 

 fourth and the other three-fourths of their length from the border ; from the first 

 of these there is a very slight linear depression, parallel to the border, running a 

 short distance across the glabella, and marking the first frontal furrow ; close 

 behind this a similar oblique frontal furrow and a transverse ocular furrow, 

 forming with the last a very indistinct upper lobe bearing one or more tubercles. 

 Basal furrow very deep and definite, truncating the glabella, and followed by a
