of the first loreal, the presence of two nuchals on each side, 
and sixteen plates under each fourth toe. The ‘scale counts 
around the body and along the back are twenty-two and fifty. 
Distribution.—This lizard was found only on Amami O 
shima. 
Remarks.—This lizard must be rather rare; for of eighty- 
one specimens of this genus taken on Amami O shima only 
two are of this species, the others being Eumeces marginatus. 
Eumeces barbouri is practically a Ewmeces latiscutatus with 
the scales around the middle of the body reduced in number to 
twenty-two. 
The presence in the Loo Choo Islands of a close relative 
of Eumeces latiscutatus is one of the most interesting facts 
brought out by these collections, since it affords, as I believe, 
the first definite evidence of a former land-connection between 
these islands and Japan proper. 
It is a pleasure to name this lizard in honor of Mr. Thomas 
Barbour of Harvard University. 
Eumeces marginatus (Hallowell) 
Diagnosis.—One azygous postmental; no patch of much 
enlarged scales on back of thigh; no postnasal; posterior 
loreal long, usually in contact with three supralabials; sixteen 
to twenty plates under fourth toe; twenty-six (rarely twenty- 
eight) scales around middle of body; young with one median 
and two lateral light lines, the latter narrow and separated 
by not less than width of two scales, lower lateral line sepa- 
rated from forelimb by less than distance between lateral lines, 
and running at about the level of top of hind limb but below 
top of ear; scales of first row on each side of middorsal line 
wider than those of next dorsal rows; superciliaries not more 
than eight; upper lateral line narrow, confined to scales of 
third row from middorsal line. 
Variation.—We have received only eleven specimens of 
the Eumeces of Okinawa. All have one azygous postmental, 
no postnasals, upper temporal largest, frontal in contact with 
frontonasal and with three supraoculars of each side, seven 
supralabials, and posterior loreals much longer than high. 
Both posterior loreals touch three labials except in No. 21641,
