Helminthopliaga luciw — Lucy's Warbler. 



Spec. char. — Above light ash-gray, with partially concealed spot 

 on vertex, and the upper tail coverts chestnut brown. Quills and 

 tail tinged with brown, edges of primaries and coverts paler ; be- 

 neath white, tinged with yellowish, this color extending to lores and 

 around eyes, forming also a faint line above and behind them. 

 Quills beneath plumbeous, tail feathers also, the outer edged with 

 white internally, and with a white patch on inner web near the end. 

 Iris brown, bill black above, bluish below, feet pale lead color. 

 Length 4.25 inches ; extent of wings, 6.50 ; wing from carpus, 

 2.25 ; tail, 1.50 ; tarsus, 0.65 ; middle toe and claw, 0.95 ; bill 

 along ridge, 0.35 ; along gape, 0.45 ; depth at base, 0.15 ; width 

 a little more. Specimens vary a little, over or under these meas- 

 urements. Female differs in small size and duller colors only. 

 Agrees very well in generic characters with the other species, but 

 has the first quill shorter than the three next, and the tail shorter 

 in proportion. 



This is the second species of the genus discovered in New Mex- 

 ico since the publication of Prof. Baird's Report on Birds, Vol. IX, 

 P. R. R. Reports. The other, H. vircriniop, is figured and de- 

 scribed in the volume of plates published by Baird, Cassin and 

 Lawrence, to complete the illustrations of new birds of North 

 America. 



This bird was common at Fort Mojave, near lat. 35°, in the Col- 

 orado Valley, where it arrived about March 25th, and remained 

 until I left there, the twenty-eighth of May. I saw none along 

 the Mojave river, on the route westward. I collected five male 

 specimens and one female. 



Prof. Baird thinks with me that the following will undoubtedly 

 prove a new species, after a comparison of specimens: 



Xerobates agassizii — Agassiz Land-Tortoise. 



Spec. char. — Young., with the carapax higher and more arching 

 than in X. caroUnus, the margin serrate all round, the primary 

 disks of the scales projecting from a tenth to an eighth of an inch. 

 Color of primary disks entirely pale yellow, the annual rings of 

 growth only being dark brown. (Young just hatched probably all 

 yellow.) 



Remarks. — Closely resembles X. carolinus, the " Gopher " of 

 Florida and the other Cotton States, of which no descriptions ac- 

 cessible are full enough to enable me to point out all the differences. 

 But as another species intervenes between the range of that and 

 this one, namely, X. herlandieri of Agassiz, found in Southern
