Summit subround. The nasal bones are flat, with broadly rounded 
extremity, and are much wider than long. 
The width of the nasals at the base of the horns is 116 mm. ; length 
of do. from do., 70; diameters of ba.ses of horns; anteroposterior, 94; 
transverse, 67 ; length of horn from nasal notch, 160; width of muz- 
zle at bases of horns inclusive, 160.

Elotherium foarctatum sp. no 
ramus with condyle, which supports all of the molar teeth. The 
species differs from the E. morfonii, with which it agrees nearly in size, 
in having all the premolars in a series uninterrupted by diastemata, 
except a very short one between pm. iii. and iv. The second premo- 
lar is the most elevated, and the third and fourth are abruptly smaller. 
The fourth has one compressed grooved root. The molars are jjeculiar 
in having the two anterior cusps elevated above the three posterior 
ones, as in Mioclaenus sp. The posterior, or fifth tubercle, is well 
developed, especially on the m. iii. 
Length from condyle to edge of canine alveolus, 295 mm. ; do. to 
last molar, 125 ; do. of true molar series, 67 ; do. of m. i., 22 ; width 
of do., 13; elevation of p.m. ii., 21 ; length of ba.se of crown do., 
28 ; depth of ramus at m. i., 55. — E. D. Cope. 
Geological News.— General.— A geological map of the north- 
ern part of Tunis was recently presented by M. Rolland to the French 
Geological Society. According to a small transcript of the above in 
the Bulletin, by far the greater part of this region is Pleistocene or 
Pliocene ; but there is a ma.ss of Eocene between Bizerte and Cape 
Farina, and two others east of the Gulf of 'i'unis, besides a much 
larger mass west of Bizerte. Considerable areas of upper Cretaceous 
also exist west and southwest of Bizerte. On the edge of the Gulf of 
Tunis the Djebel Bou Kournine rises to a height of 689 metres, and is 
the first of a series of mountain ma.sses which follow each other toward 
the south and southwest for 75 kilometres, and which culminate in the 
Djebel Zaghouan (1340 m.) These mountains are of coralligenous 
marble, compact, full of debris of encrinites, etc., but as a rule are 
without determinable fossils. A marly stratum ui)on which they rest 
has debris of belemnites. Some remains of ammonites that have l)een 
found in the marbles seem to i)rove that the latter are of Jurassic age.
