creases gradually and rather uniformly from die fourth tooth to the 

 first ; in P. (sdium there is the same gradual increase from fourth to 

 second, and then an obviously and abruptly greater increase from 

 second to first (see pi. i, figs, i and 2). The relative lengths of the 

 first and second teeth, measured along the median line of the grinding 

 surface is as follows in seven specimens of each species : P. hylceimi, 

 pm*, average 6.1 ; m^, average 5.1 ; ratio of premolar to molar 119.8; 

 P. cedium, pm^ average 7.6; m^, average 5.6; ratio of premolar to 

 molar 135.7. 



CAPROMYS PILORIDES Desmarest 

 Plate I, fig. 4 



San Gabriel (culture deposit). — Complete nasals and turbinates, 

 I ; right mandibles (all toothless), 5 ; upper incisors, 2. 



These specimens were found near together in the San Gabriel 

 kitchenmidden at a depth of about three feet. They do not differ 

 from the corresponding parts of Cuban skulls of Caproniys pilorides 

 in any way that I can discover. Consequently I have no doubt that 

 the animals to which they pertained were brought to the cave as food, 

 either by the Indians or by early European sailors. 



QUEMISIA GRAVIS Miller 

 Plate 2, fig. 3 



Boca del Infierno: — Distal half of right femur, i ; proximal ex- 

 tremity of left ulna, i. 



Both fragments (pi. 2, fig. 3) were found at a depth of about four 

 feet in the kitchenmidden near the south entrance to the outermost 

 of the two caves. 



As compared w'ith the corresponding part in the Porto Rican 

 Elasmodontomys the distal extremity of the femur has a reduced 

 antero-posterior diameter (ratio to lateral diameter about 78 instead 

 of 92.5 and 93.6 in two Elasmodontomys) ; the shaft is more flattened 

 on its anterior aspect and less flattened on its posterior aspect ; and 

 the antero-posterior diameter at middle of shaft is less in proportion 

 to the transverse diameter. 



As compared with the femurs of Isolohodon and Plagiodontia from 

 the Samana region this fragment is at once distinguishable by its 

 strikingly greater size. It appears to correspond perfectly with the 

 opposite end of the femur of Quemisia that I found in one of the 

 caves near the Atalaye Plantation, St. Michel, Haiti ; and its presence
