FORT UlSriOISr of crazy mountain field, MONT. 113 This delicate species differs so much from Prodiacodon puercensis that the generic reference is not at all certain, but the only alternative would be erecting a new genus, which is highly undesirable at present. The present form is apparently a typical leptictid, peculiar only in minute detaUs, and as close to Prodiacodon as to any other defined genus. It is almost equally close to Leptacodon, but its reference there would make the generic definitions almost unpossible to frame adequately. Th

FORT UlSriOISr of crazy mountain field, MONT. 113 This delicate species differs so much from Prodiacodon puercensis that the generic reference is not at all certain, but the only alternative would be erecting a new genus, which is highly undesirable at present. The present form is apparently a typical leptictid, peculiar only in minute detaUs, and as close to Prodiacodon as to any other defined genus. It is almost equally close to Leptacodon, but its reference there would make the generic definitions almost unpossible to frame adequately. The type is the only known specimen. Its dimensions are as follows: Length P2, ; width P., ; length P^, ; width P„ ; length M3, ; \v4dth M3, Genus LEPTACODON Matthew and Granger, 1921 LEPTACODON LADAE Simpson Figure 15 Leptacodon ladae Simpson, 1935d, p. 228. r?/^e.— no. 9640, right lower jaw with P4-M3.
