. Bulletin - New York State Museum. Science. l60 NEW YORK STATE MUSEUM former, comparison can go no farther. Dalmanites veiti has a type of cephalon quite unlike that of D. dentatus which is dentate on the entire periphery. Locality. This species has been found only in a loose block from the limestone ridge behind Peninsula, Gaspe Basin, in association with D. phacoptyx, Phacops logani gaspensis, Platyceras conulus, Anoplia nucleata and other species of the Grande Greve fauna. Lower Devonic. Grande Greve, P. Q. Dalmanites whiteavesi nov. This species is represented by a series of small pygidia some- what of the type of that part in D. anchiops Green but more particularly like that of D. m e e k i, figures of which may be found in Walcott's Palaeontology of the Eureka District, 1884, pi. 17, fig. 5, and Palaeontology of New York, 1888, v. 7, pi. 11 A, fig. 29, 30;. Dalmanites whiteavesi that is, rather short and subtriangular but with rounded margins and an extended, slender caudal spine. The axis is moderately broad and convex bearing seven or eight segments which are well rounded and the pleural ribs are of the same number, flat on top with narrow intervals and each is grooved by a fine line. The margins of the shield curve slightly outward uniting behind to form a spine which has about one fourth the length of the shield. It is narrow, ends acutely and is slightly upturned. As a whole the shield is shorter, relatively broader and has more segments than does D. m e e k i. The latter is from the lower part of the Devonic series in Nevada. Lower Devonic. Grande Greve, P. O. Dalmanites gaveyi nov. We are here presented with a species in which the frontal margin of the head bears a slight, simple, lobed and blunt extension with- out accessory processes or crenulations similar in effect to that of D. g r i f f o n i. This is a structure after the type of D. v i g i 1 a n s. Please note that these images are extracted from scanned page images that may have been digitally
