40 FLORIDA GEOLOGICAL SURVEY-NINTH ANNUAL REPORT. 
anserine form. It had a length of about that of Dendrocygnus 
autumnalis, and it very possibly may have belonged to a bird of that 
genus—that is, a Tree Duck. It should be set aside until further 
material be brought to light from excavations at Vero later on. 
LARUS VERO, sp. nov. 
(Plate II., Fig. 21.) 
Pleistocene, Stratum 3, Vero, Fla. 
The type bone. 
No. 6933. Left carpo-metacarpus of an extinct gull, of a 
larger species than Larus atricilla, or a larger bird among the terns 
than Sterna maxima. This bone runs very close with respect to 
characters among the gulls and terns. Still, everything else being 
equal, the head of the bone is proportionately larger in the terns, as 
compared with its shaft, than it is in the gulls. This can be appre¬ 
ciated by comparing Figures 21-23 of Plate II. Then the general 
morphology of the proximal extremity of the bone is somewhat dif¬ 
ferent, which may also be appreciated by critically comparing the 
aforesaid figures. The specimen is imperfect, the shaft of medius 
metacarpal having been broken off and lost. Extreme length 5.75 
centimeters. 
For this new and now extinct Gull I propose the name of Larus 
vero, the specific name being for the locality where it was discov¬ 
ered. 
SHAFT OF AN ULNA; BIRD. 
(Not identified.) 
No. 6793. Stratum 3. This bone belonged to some large bird of 
an unknown species. The extremities having been broken off and 
lost, it is too fragmentary for identification or reference. It should 
be set aside until further material conies to light during future 
excavations in the same locality. 
Washington, July 20, 1917. 
Number 6931.—Proximal two-thirds of a left tarsometatarsus, 
nearly perfect, of some wader (adult). This bone agrees very 
closely with the corresponding one, or part of one, belonging to a 
skeleton of an adult Egret ( Herodias egretta) in the collections of
