Nacional, of Saa Jose. This material differs from that described in former 

 papers in the fact tliat it was mainly obtained on the Pacific slope of the 

 country,* while the latter was collected on the Atlantic slope and on the 

 central plateau. In the enumeration which follows, the localities are 

 mentioned in greater detail. The total number of species sent by Mr. 

 Cherrie is thirty-three, of which sixteen are additions to the fauna of Costa 

 Rica, and nine are new to science. I hope to be able to figure these spe- 

 cies at an early day.

Urodela. 

 Haptoglossa ruESSiCAUDA, gen. et sp. nov. 



Char. gen. — Group of Thoriinae, which includes Thorius Cope and 

 Typhlotritonf Siejneger ; hence the vertebrae are opisthoccelous and the 

 carpus and tarsus not ossified. Tongue adherent in front and by the mid- 

 dle. Digits not distinct, 4-5. 



This genus is of much interest as the first one discovered in Tropical 

 America in which the tongue is not boletoid in form. It seems also that 

 the relation of this form of the western coast to those of the east coast 

 in this group is the same in Costa Rica as that which prevails in North 

 America. It is well known that no species of salamander, with a bole- 

 toid tongue, is found on the Pacific coast of North America. 



Char, specif. — Form slender, limbs very small. Length of tail equals 

 that of the body without the head. Length of head contained in that of 

 the body to the vent, seven and a half times ; the width less than the 

 length. A gular and nineteen costal folds, the latter not very distinct. 

 Fore and hind limbs each equal to three intercostal spaces. Digits indi- 

 cated by emarginations of the foot border. Vomerine teeth in two moder- 

 ately arched transverse series, not produced posteriorly on the middle line, 

 hence well separated from the rather wide single patch of parasphenoid 

 teeth. Tongue rather small, oval. Nostril of moderate size, situated well 

 anteriorly. Eye, large. Tail compressed from near base to apex, with a 

 median dorsal, but no ventral groove, and well-marked vertical grooves. 



Color, uniform black ; under side of head and tail a little paler than 

 other regions. 



Measurements. mm. 



Total length 62 



Length to posterior angle of mouth 4 



Length to fore limb 8 



Length to hind limb 28.5 



Length to base of tail 31.5 



Width of head at angle of mouth 3 



This species resembles superficially the three small salamanders of 



* The only exceptions are Nos. 338, 339, and 347.
