2. Description of a new genus of Batrachians from Swan 

 River. By Dr. H. Schlegel, Curator of the Royal 

 Zoological Museum, Leyden. (Extracted from a Let- 

 ter to J. E. Gray, Esq.) 



" The following notice I hope is sufficient to give an idea of a new 

 Toad which was discovered at Swan River by Dr. Pries : — 



" Myobatrachus, n. g. 



" Tongue small ; no teeth except two small horizontal fangs in the 

 intermaxillary bone ; eustachian tubes separated, opening behind the 

 eyes. Legs short, enveloped at the base in a duplicature of the skin 

 of the sides of the body. Fingers 4, the second longest ; toes 5, cy- 

 lindrical, tapering, not armed. Eyes lateral, middle-sized. 



" Myobatrachus paradoxus. 

 Above brownish grey, beneath greyish. 

 Hub. Australia; Swan River. Mus. Leyden. 

 The Prince of Canino has made for this animal a family, which he 

 has named Myob.\trachid.e." 



Mr. Gray observed, that a toad which he described and figured in 

 Capt. Grey's Travels in iVustralia, under the name of Breviceps 

 Goiildii, agrees with the animal described by Dr. Schlegel in all par- 

 ticulars, and especiallj' in possessing the two horizontal horny appen- 

 dages on the intermaxillary, which Dr. Schlegel described as hori- 

 zontal fangs ; they are partly sunk into the integument of the palate. 

 Admitting the propriety of the proposed generic distinction, the 

 animal will therefore now stand in the catalogues as jSli/ohairachus 

 Gov Ida. 



The presence of the teeth in the intermaxillary separates this animal 

 from the Breviceps of South Africa.

Prionacalus Atys. 



In the 'Annals and Magazhie of Natural History,' vol. xv. p. 108, 

 I have described under the name oi Prionacalus Cacicits, a curious 

 genus from Mexico, allied to Bsaiiflofjnathvs, G. R. Gray. I re- 

 garded the two specimens as male and female of the same species, 

 but it would seem that they are both males, and as they are con- 

 siderably different, must be different species ; what -was deemed the 

 male may retain the name Prionacalus Cacicus ; it is figured on 

 PI. Vin. fig. 1. of the above volume. The other sj)ecimen may be 

 named Prionacalus Ip/iis ; it is figured on PI. VIII. f. 2. Since the 

 above we have received a third species from the Andes of Pern, where 

 it was found by Prof. Jameson of Quito ; the following short specific 

 characters may distinguish the three : — 



P. Cacicus.
