and shows some affinities with the larger jack snipes found in South Amer- 

 ica. It seems thus to introduce an element hitherto unknown in the 

 West Indian Fauna. 



Oreopeleia larva, sp. nov. 



Characters. — Metatarsus similar to that of Oreopeleia leucometopius 

 Chapman from Santo Domingo, but distinctly longer. 



Description. — Type, Cat. No. 4923, Dept. Vert. Pal., American Museum 

 Nat. Hist., left metatarsus, from La Cueva Clara, near Morovis, Porto 

 Rico, collected in July, 1916, by H. E. Anthony. 



External glenoid facet concave, with a high external border near center, 

 rudely elliptical in outline; internal glenoid facet also with high external 

 border, nearly circular in form; intercondylar prominence strong, in form 

 resembling a truncated cone, with the apical surface sloping anteriorly; 

 anterior semilunar groove very slight; anterior surface of bone below 

 head excavated in a long groove that lies mainly on the inner side; both 

 external and internal superior foramina present, the first penetrating 

 through to opposite side; insertion of tibialis anticus tendon slight; outer 

 anterior margin ridged to a point below the anterior groove where the 

 entire bone shows a broad flattened surface; inner crest of talon very 

 slightly indicated; outer crest strong and heavy with the posterior semi- 

 lunar groove well developed; outer head of talon with one median per- 

 foration and two external grooves, that are not closed; posteriorly the 

 talon is produced in a thin sharp ridge that descends rapidly to merge 

 with the body of the bone at the anterior third of its length; junction of 

 talon with shaft marked externally by a low ridge that curves anteriorly; 

 internal margin of bone produced anteriorly as a thin plate that slopes 

 in a curve to join the talon and that has a sharp outer margin; shaft 

 greatly flattened distally; a raised line extending from the crest of the 

 talon down the center of the shaft behind to curve outward finally to the 

 base of the outer trochlea; another less definite line passes to the inner 

 trochlea; inner trochlea produced outward and backward as an angular 

 projection with a flattened lateral point; middle trochlea projecting well 

 beyond other two, rounded in outline, flattened laterally, with excavated 

 sides and a deep median channel; outer trochlea strong and heavy, pro- 

 duced outwardly and posteriorly and excavated behind, where it is also 

 heavily grooved; a large external inferior foramen and a faintly indicated 

 internal one. 



Measurements. — (Of type.) Total length 39.5 mm., smallest transverse 

 diameter of shaft 2.5 mm., breadth of head 6.7 mm., breadth across trochlea 

 7 mm., depth through talon 6.5 mm. 



Range. — Known from Cueva Clara and Cueva Catedral near Morovis, 

 and a cave on the property of Don Gervacio Torafio near Utuado. (Ex- 

 tinct.) 



Remarks. — The diagnosis given for this Quail-Dove is necessarily 

 brief because of lack of osteological material for comparison, but is suffi- 

 cient to point out the character of greater length of leg distinguishing
