liead rciHlcrs tlio i)rop(>rtion.s of form Hlniilar to tlio.sc in II. curia 

 from wliicli there is M(»me dilllealty in distingni.sliing it. Tlio latter 

 may be known by the small size and lack of gnlar vesicle among the 

 males. The muzzle is more obtuse than in the typo of II. cadaverina, 

 but one specimen of Laticeps is similar in this point; there is no labial 

 brown border, but we have it much obscured in a Laticeps ; the diam- 

 eter of the eye is les.s, measuring less on the humerus; the digits much 

 broader and shorter, with the largest pallets equaling the tympanum, 

 while they are more elongate and slightly proportioned in Laticeps ami 

 Regilla vera. There is a thin tarsal ala, extending to the cuneiform 

 bone, which is scarcely marked in the Laticeps. There arc more lateral 

 dorsal 8i)ot8. These characters can not now be proven evanescent, so 

 that this allied subspecies may be accepted.
