THE BATRACHIA OF NORTH AMERICA. 457 



moderately couvoluted. The vessels of the mesentery are lar^e. The 

 mesenteric veiu runs along the inferior edge of an elongate body, which 

 is either the spleen or the pancreas. It extends from the stomach for 

 a distance equal to one-third thelengtli of the visceral cavitj", terminat- 

 ing near the anterior testis. The liver is large and long, extending 

 from the heart to near the anterior testis. It is divided by a median 

 groove for most of its length, iu which the base of the mesentery is at- 

 tached cardiad of the large gall-bladder. The anterior part of the 

 liver forms a median lobe, which extends for a short distance below 

 the alimentary canal. 



There are two pairs of testes, the anterior the longer. The kidneys 

 are flat, oval bodies, lying on each side of the middle line, immediately 

 above the rectum. They open by a short ureter into a fold of the 

 cloaca. The urinary bladder is large and long, extending forwards as 

 far as the anterior extremity of the anterior testis. (Plate xlty.) 



SALIENTIA. 



Viscera.— The corpora adiposa are elongated transversely, and fre- 

 quently fissured at the distal extremity. (Plate lvii.) 



The ductus mUlleri is i)resent in Bufo, Scaphiopus, and other genera, 

 but is wanting in Eana, except Bana virescens (Sedgwick). 



The urinary bladder is large, and is extended from side to side of the 

 inferior i>art of the abdominal cavity. Its anteroposterior extent is 

 small. 



The Kev. W. J. Holland informs me that he has observed in Japan 

 arboreal nests of Batrachia Salientia, in which the embryos developed 

 into tadpoles, which reached a length of nearly an inch, before leaving 

 the nest. The nests are made in willow trees at a distance of from 12 

 to 14 feet above the water. The dried remains of a nest containing a 

 good many dried ova and tadpoles was sent me by Mr. Holland. The 

 latter are distinguished by the presence of a large persistent food-yolk, 

 as in various Salientia of division II of the table on pages 238 and 239. 



BUFO Laur. (p. 261). 



Insert at bottom of page 261 in table of species: 



Olio metatarsal tubercle; cranial crests parallel, not produced posteriorly; 

 profile descending; muzzle produced beyond mouth ; skin smooth be- 

 low ; a lateral band B. aduncus. 



One metatarsal tubercle ; cranial crests separated, sending a branch 

 inwards posteriorly; parotoid gland triangular; a lateral light 

 baud B. vaJliceps- 



BUFO ADUNCUS, sp. nov. 



This very distinct species has the cranial crests of the B. lentiginosus 

 type, more especially resembling the B. l.fowlerii. It differs especially 

 from that species in the very short, wide head, with depressed muzzle 

 overhanging the mouth, in the perfectly smooth inferior surfaces, and 

 in the coloration, as well as m various minor details.
