LOVEINA ZEPHYRI Simpson 



U.S.N.M. No. 184;59, portion of a left mandible with part of P„ tlie 

 base of M,, and M, and M3 (loo. No. 48FR76) . 



This specimen is provisionally referred to this species on the basis 

 that Mo and M3 agree Avith those of ? Z. vespertina (ISIatthew) better 

 than with those of any other genus. It ditl'ers from that species in 

 the proportionally shorter Mi and ^lo, in the broader trigonid, and in 

 the presence of a minute entoconid on the heel of M3. Since M2 and 

 M3 are unknown in the genotype any attempt at comparison of the two 

 specimens would be futile.

STYLINODON CYLINDRIFER (Cope) 



U.S.N.M. No. 18440, portion of right canine (loc. No. 48FR7G). 



This specimen is referred to S. cylindrifer- on the basis of the dis- 

 tribution of the enamel, which is in two bands, one on each side of 

 the tooth. It is of uniform thickness and width and shows the obso- 

 lete vertical striation and the stronger transverse growth lines which 

 Cope (1884, p. 192) describes for the type of the species. The cement, 

 which covers the areas between the enamel bands, overlaps the enamel 

 for a short distance on each side, Imt there is no evidence that the 

 bands were covered.
