The generic characters will then he 



Ethmoid arch superiorly cartilaginous ; prefrontals narrow, longitudinal 

 widely, separated. Distal phalanges slender, with transverse limb ; no meta- 

 tarsal shovel ; tongue bifurcate. 



Ranula af f i n i s. Rana affinis and Ranula gcelmerii (young) Peters, Mon- 

 atsber, Berlin. Venezuela. 

 Though I employ the name given to this species for the genus, I am not 

 positive as to the condition of the distal phalanges. 



Ranula sp. nov. 0. Salvin ; Vera Paz, Venezuela. 



Ranula coe rule o pun ct ata. Rana do. Steind., Verhandl. Bot. Zool. 

 Gesselsch. Wien, 1864, 264. ? South America. 



Ranula chrysoprasina. 



The species is allied to the last, but has a relatively shorter muzzle and 

 limbs. Nostril nearer end of muzzle than orbit (equidistant in coeruleo- 

 punctata); muzzle 1 1-5 th orbit (1 2-5th Steind.) Under jaw anteriorly 

 abruptly truncate. Canthus rostralis straight, strong, muzzle acuminate from 

 its extremity, projecting ; loreal region vertical. Tympanum elliptic two- 

 thirds orbit. Vomerine teeth weak, in convergent fasciculi behind opposite 

 nares. Skin shagreened above, a glandular fold on each side. The longest 

 linger cannot be extended to vent ; heel to middle loreal region. Toes fully 

 not widely palmate, three distal phalanges of fourth free ; one minute meta- 

 tarsal tubercle. 



Color brilliant leek green, the groin and belly approaching golden ; a golden 

 band from lip to shoulder, and faint one on each side back. Limbs above, 

 and tarsus and forearm below, black, the femur with a few golden spots on 

 Mack ground behind. Head dark above, from eye to shoulder black ; below 

 pale yellowish green immaculate, except some dark shades on sternal regions. 



Length of head and body 1 in. 9 1.; of fore limb 1 in. ; of hind limb 2 in. 

 7 "5 1. Costa Rica. 



Steindaehner represents much less palmation than exists in our specimen. 



It is interesting to observe how that this Raniform type, while preserving 

 its definitive features in this outlying region of its distribution, and within 

 the limits of the lower fauna? of South America and Australia, offers the low- 

 est condition of cranial structure consistent with this type, i. e., the imperfec- 

 tion of its ethmoid and prefrontal bones. 



Golostethus latinasus gen. nov. 



By this name I propose to characterize a genus of Ranida?, the type of which 

 .is the Phyllobates latinasus m., Pro<\ Acad. Nat. Sci. 1863, 48. 



The sternum is Raniform without manubrium, and with membranous 

 xiphisternum, quite as in the Bufoniform genus Dendrobates, from which the 

 presence of very well developed teeth only separates it. It will form a Group 

 I. of Fam., Ranidas before that occupying that place in System Batrachia Sa- 

 lientia, Nat. History Review, 1865, and tending towards Bufoniformia. The 

 characters are 



Group I. No manubrium, xiphisternum membranous. External meta- 

 tarsi bound ; distal phalanges with terminal transverse limb. 



Character of genus. Digits free with dilatations ; no vomtrine teeth ; pre- 

 frontals widely separated by the largely produced bony superior ethmoid 

 plate. 



Bufo c o c c i f e r 6p. nov. 



Parotoids round semiglobular. Muzzle narrowly rounded, nearly as long as 

 orbit. Strong bony, canthal, pre-, sub-, and postorbital, supratympanic and 

 supraorbital ridges ; the last regularly curved and sending parietal branch to- 

 wards the median line ; the first rapidly converging, leaving only a gutter 

 between. Tympanum .one-fifth orbit. Everywhere minutely tubercular,
