204 ON THE FAMILIES OF THE RANIFORM ANURA. 



of Hypsiboas crepitans, I have founds feathers of birds, some of brilliant colors, 

 which the animals had mistaken for insects. Both the nareal meatus of the last 

 named contained feathers, and one projected from each nostril, probably forced 

 through them by the usual upward motion of the tongue in endeavoring to expel 

 them. 



The generic name is from -Aqyliz, a lattice. 



Calamita eoLiCHOPSis Cope, sp. nov. 



This species may be contrasted with the Australian C. c y a n e a, as follows : 

 Head short, truncate, covered with thickened derm ; mandible not yellow 



margined ; hind limbs shorter, heel to orbit, cyanea. 



Head elongate, oval, covered with thin skin ; mandible with a yellow, 

 below brown edged, margin ; limbs longer, heel to end of muzzle and 



beyond, dolichopsis. 



Habitat. Ajnboina. 



This large species much resembles its congener in color and differs chiefly as above. 

 The following measurements of two specimens of equal length of body will indicate 

 this :

The glandular folds about the rictus oris are less marked in the present species than 

 the C. cyanea, and the yellow mandibular margin is prolonged to over the bra- 

 chium. Tympanum half orbit ; tongue oval ; crests of the vomer supporting teeth 

 little elevated, less so than in C. c y a n e a . Breast derm not areolate; areolae of sides 

 and behind axillae many (ten) times larger than those of abdonien. Outer web of 

 fingers opposite end first phalanges of penultimate digit (middle, C. cyanea). 

 Green color on outer metatarsus and toe only.
