 I spoke to him of the peculiarities of a form of Cave Sala- 

 mander found near Brookville. They had been called 

 Spelerpes longicaudus, but I was satisfied they were not that 

 form, yet I could not satisfy myself as to their identifica- 

 tion. He expressed a desire to see one alive, since I spoke 

 of their bright color in life. Through the kindness of Mr. 

 Bayard Quick, he was presented with two living specimens, 

 and I was enabled to furnish him an alcoholic specimen 

 from my collection. These he took with him to Philadelphia. 

 I take the liberty of presenting Prof. Cope's remarks concern- 

 ing these specimens entire, since it may be possible some, to 

 whom this paper will come and who are interested, may not 

 have seen the paper quoted: "The three specimens repre- 

 sent young, middle-aged and mature individuals, which have 

 passed their metamorphosis. They agree nearly in their 

 characters. They belong to a species which resembles the 

 Spelerpes /oiiiiicaiidus, but are distinct in form, color and 

 habits, and belong, moreover, to the genus Gyrinophilus. The 

 premaxillary bones are of feeble structure, and the spines are 

 distinct and widely separated, contrary to the structure of the 

 genus Spelerpes. The mature individuals, of which Mr. 

 Butler possesses several, are much more robust than those of 

 S. lo7igicaiidits, having a short body and relatively long 

 preaxillary region and head. With this the tail is as long as 

 in the .S". lo7igicaudiis, and is similarly compressed. The en- 

 tire animal is larger. The color is different from that of the 

 5". lono^icaiidus. It is vermilion-red, as in ^. ruber, and the 

 superior surfaces of the head and body are irregularly spotted 

 with dark brown. The sides of the tail are similarly irregu- 

 larly brown-spotted, the spots not showing the least tendencj^ 

 to form the vertical bars characteristic of the S. lo7igicandiis. 

 The form of the series of vomerine teeth is different. Instead 

 of commencing at the posterior border of the internal nares, 

 they commence opposite to the anterior border of the same, 

 and .send posteriorly a .short branch along the internal border 

 of the choana, thus giving a hook-shaped outline to each 

 series. The proportions are as follows : 



" Width of head five times in length of head and body to 

 groin. Tail one and a half times the length of the head and 

 body. When the limits are extended, the posterior toes reach
