NORTH AMERICAN FAUNA. 



The type of this species is Dr. Edward Palmer's No. 129, from 

 Acapiilco, Mexico, collected in 1894-95. To this species I would refer 

 specimens collected by Frank Lamb near Yilla Union, State of Sinaloa, 

 January, 1893 (No. 428), and flowering specimens by W. C. Wright 

 from the head of Mazatlan Eiver, January, 1889 (No. 1292), and also 

 those collected by J. N. Kose at Eosario, Sinaloa, July 10, 1897 (No. 

 1592), and July 22 (No. 1822). The latter two specimens are not in 

 flower and their reference here is attended with some doubt. The 

 seeds are larger and the i)ods less constricted between the seeds. Here 

 also belongs E. W. Nelson's No. 4303 from the Tres Marias, collected 

 May, 1897. I have tentativelj^ referred to this species E. W. Nelson's 

 No. 2(399, taken at an altitude of 480 meters, uear Santo Domingo, State 

 of Oaxaca, June 18, 1895. It has similar pods, but is described as 

 being but G to 12 cm. high and has more bluntish leaflets. 



Dr. Palmer says this tree flowers in January, and is often used for 

 hedge fences. It diflers from all other Mexican species Avhich I have 

 seen in its white lanate banner. Its one-toothed calyx suggests E. 

 rosea, but in the latter the calyx is described as obliquely truncate.

Lonchocarpus sp.

 Ateleia ( ') sp. 



Without flowers or named specimens tor comparison it is imi:)ossible 

 to name this plant definitely. If it belongs to the geuus Ateleia it is 

 lierhaxDS A. i)terocari)a, the only species known from 3Iexico. A shrub 

 or small tree 3.5 to 10.5 meters high. May 3 to 25 (No. 4186).
