126 MRS. E. M. REID ON TWO [vol. lxxvi, 



sunk, not prominent. Except the two sections Microcarpce and 

 PidclierrimcB all fruits of Cratoegus are large, also a number of 

 them have two or three, not five, stones. The nearest living 

 species that I have been able to find is C. cordata ; but the style 

 is not so prominent, and the carpel not so symmetrical as the fossil: 

 it tends to be nodular, both on the ventral faces and at the dorsal 

 angles. 



The species is the same as that described from the Peuverian as 

 Cotoneaster acuti carpal 



Crataegus microcarpa, sp. nov. (PI. VIII, figs. 26-28.) 



Carpella quinque. parva, confragosa, lata, supra medium latissima, 

 apice complanata ; stjdus terminalis, exsertus. 



Berry globose ; carpels five, broad, broadest above the middle ; 

 ventral margin straight, convex or angled at the middle ; dorsal 

 surface convex, contracted above at the free area, flattened at the 

 apex ; a median rib on the dorsal surface ; surface rugose all over ; 

 junction of adherent and nude areas marked by a deep depression 

 across the dorsal surface at a fifth of the distance from the apex ; 

 on the ventral angle junction of areas half-way or less from the 

 apex ; st}de terminal, projecting. 



Endocarp : length = 3 mm. ; breadth = 1*6 mm. 



Several loose carpels and three united carpels were found. 



The species is very near to the American C. spathirfata Michaux, 

 but this is larger, not so rugose, and the style is shorter and less 

 prominent. 



Crat^gits nodulosa, sp. nov. (PI. VIII, fig. 25.) 



Carpella quinque, parva, angusta, infra medium latissima, 

 superfieie dorsali ob sulcos altos uno mediano uno transverso apice 

 nodulosa, stylo terminali exserto. 



Carpels five, narrow, elongate, broadest below the middle ; 

 ventral margin straight or slightly convex ; dorsal surface uni- 

 formly convex in the adherent area, nearly straight and sub-parallel 

 to the ventral margin in the nude area, flattened at the apex, much 

 contracted in the nude area, where at the apex, on either side of a 

 median depression, are the halves of tubercles, which (when the 

 carpels were united) must have formed a ring of five tubercles 

 round the style ; junction of adherent and nude areas at a third of 

 the distance from the apex on the dorsal surface, and three-quarters 

 of the distance from the apex on the ventral margin ; style ter- 

 minal, projecting above the flat-topped carpel. 



Carpel: length = 2 - 6to 2 - 8 mm. ; breadth = P2 mm. 



Two perfect carpels and several fragments. 



The median dorsal groove would seem to indicate that this 

 should be placed in the section Pitlclierrimce.
