from a point just behind the last molar towards the inferior 
edge some distance in advance of the angular process. 
Below and in front of this ridge there is another large 
depression, Jn all other bears the hollow of the coronoid 
is bounded inferiorly by a crest running horizontally for- 
wards from the angular and curving upwards on a level with, 
or in front of, the anterior edge of the root of the coronoid 
process, aud the adjoining surface of the mandibular ramus 
has no depression. Perhaps in Jremarctos the depression 
of the coronoid (masseteric fossa) may be described as very 
large and completely divided by a bony ridge into an upper 
and a lower portion by the above- mentioned crest of bone, 
but the musculature of this region requires, | believe, 
working out. 
X.—WNote on the Subgenus Paradownesia, Gestro. 
By 8. Mavuix, B.A. (Cantab.), F.E.S. 
In the ‘Annali del Museo Civico di Storia Naturale di 
Genova’ (serie 2a, vol. xx. (xl.), 3 Nov., 1899, p. 220), 
Dr. Gestro has published a note on the genus Downesia, 
founding Paradownesia as a subgenus of it. The characters 
on which he establishes the subgenus are stated as follows: — 
“(1) Una facies molto diversa, dipendente della forma pit 
allungatae pit stretta; (2) dagli elitri convessi, pit stretti all’ 
apice che alla base, non pit larghi del protorace e con scultura 
leggera; (3) I] capo é troncato in avanti e si avanza alquanto 
al di 1A degh occhi con una sporgenza larga rettangolare 
che in parte copre il primo articolo delle antenne.” Then 
Dr. Gestro goes on to remark that this conformation of the 
head is not found in any species of true Downesia, including, 
of course, the type. I agree with him that D. longipennis, 
Gestro (the type of Paradownesia) and other forms which he 
has described under it ought to be separated from Downesia, 
with which they have no ‘affinity, But I see no reason why 
they should formasubgenus of Downesia at all. Judging from 
the figure and description of D. longipennis (Ann. Mus. Civ. 
Stor. Nat. Genova, vol. x. (xxx.), Nov. 1890, p. 244, and Nov. 
1899, p. 220), and examining Paradownesia fruhstorferi, 
Gestro, of which a cotype exists in the British Museum, and 
also another specimen which bears a label in Dr. Gestro’s 
handwriting, determining it generically as Paradownesia, I 
am of opinion that this subgenus should be a synonym 
of Leptispa. My first reason is that the characters that 
Dr. Gestro selects for erecting Paradownesia are found in
