1902.] NATURAL SCIENCES OF PHILADELPHIA. "A^l 



Remarks.— Momphyllus cubanu.s is readily distinguishable fro... 

 M. redmani bv its small size and lightly built skull. In the general 

 form of both 'skull and teeth it is, however, more closely related 

 to the large Jamaican species than to the smaller members of the 

 genus. 



Monophyllus luciae sp. no v. 



Type.-A.dn\t male (in alcohol). No. 106,095, United States 

 National Museum. Collected on Santa Lucia Island, West Indies, 

 February 4, 1901, by H. Selwyn Branch. 



Characters.— ^iost nearly resembling Monophyllus plethodoii of 

 Barbados, but larger and with less crowded teeth. 



Color —After about a year's immersion in rum the specimens are 

 rather darker and more tinged with red than in Moaoph>jlltcs 

 cubanus, but this character may be the result of the action of the 

 preservative fluid. 



Skull and Teeth.— In general form the skull agrees with that of 

 Monophyllm plethodon, and differs from that of M. redmam and 

 M. cubanm in the large, inflated braincase, broad interorbital 

 region and short rostrum. The zygomatic arches are strong and 

 well developed, more so, apparently, than in 3/. plethodon. Ros- 

 trum broader tbau in the Barbados species. 



Teeth as in Monophyllus plethodon, except that the first upper 

 premolar is separated from the canme and also from the second 

 premolar by a narrow space, of much less extent, however, than in 

 the other members of the genus.
