Since the above wa.s written I have been able, through the kindness 

 of I'rofessor Forbes, «)f the university at Chani]»ai{jii, III., to <'xaniine 

 the type specimen of Messrs. Jtice and Davis. It ditfeis considerably 

 from the specimens above described, as follows: The muzzle is not pro- 

 tuberant, 80 that the nostril is t'(|ni(listant between the end of the 

 muzzle and the eye, as in the subspecies Areolata. The tympanic disk 

 is nearly round, and its lonj;' din meter is three-fourths tiiat of the eye. 

 This specimen has twice the bulk. In other respects it does not diH'er. 

 A very stronj; glandular thickenino' of the skin extends from tlu' eye 

 alove the tympanum, and then descends posterior to it. The eyelid also 

 is thickened. 



Two specimens (No. 138L*S) from Olney, 111., also ie(!t'ived since the 

 jibove description was written, explain these discrepancies, Thelaiger 

 of the two agrees with the tyi)e in all respects, l)ut tiie smallei', which 

 about ecjuals the type in dimensions, has the elongate muzzle of the 

 small ones that I have described above. In both the tympana are three- 

 fourths the orbit, and in neither is it decidedly oval.

Not having at hand the only known specimen of this form, I copy 

 the description given by V^ Conte. The proportions given by this author 

 imlicate that it is intermediate in pn^portions between the subspecies 

 vEsopus and tiu^ others. Thus the width of the iiead in the latter enters 

 the length 2.3;{ times, and in the R. a. areolala three times. In R. a. 

 capita it enters '2.S times. The spots are snmlU'r than in R. a. circKlosa, 

 but larger and more numerous than in R. a. (vsopiis and R. a. areolata.
