An undescribed species of Coelodus is represented by portions 
both of the upper and lower dentition from the Cretaceous near 
Beyrout, now in the Museum of the Syrian Protestant College, 
Bey rout. 
Imperfect skeletons of an undetermined species probably of Coelodus , 
from the Cretaceous of the neighbourhood of Naples, are described 
under the name of Anomiophthalmus vetustus by 0. G. Costa, Ittiol. 
Foss. Ital. (1856), p. 30, pi. iii. figs. 4, 5, and Atti Accad. Pontan. 
vol. viii. (1864), p. 116, pi. xi. figs. 4, 5. Here may also probably 
be placed the imperfectly known Pycnodus rotundatus (0. G. Costa, 
ibid. 1864, p. 82), as suggested by F. Bassani, Denkschr. k. Akad. 
Wiss., math.-naturw. Cl. vol. xlv. (1882), p. 233. 
The so-called Glossodus heckeli , 0. G. Costa (Atti Accad. Pontan. 
vol. viii. 1864, p. 109, pi. ix. figs. 12, 13), from the Cretaceous of 
Pietraroja, is too imperfect for determination (F. Bassani, loc. cit. 
1882, p. 233). 
Genus ANOMOESODUS, Forir. 
[Ann. Soc. Geol. Belgique, vol. xiv. 1887, Memoires, p. 25.] 
An imperfectly known genus. Head-bones ornamented with 
reticulating rugee ; the smaller teeth usually with an apical indent, 
the principal teeth quite smooth or with a very feeble linear indent. 
Oral surface of vomer nearly flat, with teeth of irregular sizes in 
from three to five longitudinal series; splenial dentition restricted
