Type . Detached teeth ; Palaeontological Museum, Munich. 
A species of moderate size, known only by the dentition. Teeth 
of the principal series on the splenial bone slightly arcuated, taper¬ 
ing and sharply turned forwards at the inner extremity, attaining 
a breadth about three times as great as their length ; [inner teeth 
unknown] ; teeth of the two flanking series very irregular, relatively 
small, not pitted, and mostly broader than long [perhaps succeeded 
without by other series]. Vomerine dentition very narrow, convex 
from side to side, with teeth closely arranged and not pitted: 
median teeth ovoid, the hindermost twice as broad as long ; teeth 
of the inner lateral series broader than long, almost pear-shaped, 
and their long axis oblique ; outermost teeth insignificant and 
irregularly rounded.

1 Indeterminable fragments are also described under this name by A. E. Reuss, 
Yerstein. bohm. Kreideform. pt. i. (1845), p. 9, pi. iv. figs. 27-36 (Bohemian 
Planerkalk); Pictet & Renevier, Foss. Terrain Aptien Perte du Rhone (1854), 
p. 10, pi. i. fig. 4 (Switzerland) ; Pictet & Campiche, Foss. Terrain Cretace 
St. Croix (1858), p. 65, pi. viii. figs. 24, 25 (Switzerland); H. E. Sauvage, 
Bibl. Ecole Hautes Etudes, vol. v. art. 9 (1872), p. 8, figs. 11, 12 (La Sarthe); 
and H. B. Geinitz, Palteontogr. vol. xx. pt. i. (1875), p. 301, pi. lxv. figs. 15- 
21 (Saxon Planerkalk), pt. ii. p. 217, pi. xl. fig. 33. The imperfect splenial 
dentition of a species of Ccelodus from the Planerkalk of Bohemia is also named 
Pycnodus complanatus by A. Fritsch, Rept. u. Fisehe bohm. Kreideform. 1878, 
p. 21, pi. ii. fig. 5, woodc. 47. Another splenial, perhaps of Anomceodus, is 
similarly recorded from the Upper Neocomian of Moneteau, Yonne, France, by 
H. E. Sauvage, Bull. Soc. Sci. Nat. Yonne, vol. xxxiii. pt. ii. (1879), p. 41, pi. i. 
fig. 5. 
2 The fragments from the Neocomian and Aptian of Switzerland ascribed to 
this species by Pictet and others (Pictet & Renevier, Foss. Terrain Aptien Perte 
du Rhone, 1854, p. 9, pi. i. figs. 2, 3 ; Pictet & Campiche, Foss. Terrain Cretace 
St. Croix, 1858, p. 61, pi. viii. figs. 21-23) are incorrectly determined.
