464 bulletin: museum of comparative zoology. 



The Cedar Lake record is a most remarkable one. It lends credence 

 to Nash's record for Ontario. It is of course an instance of postglacial 

 spreading, and indicates that D. fusca in times directly after the 

 glaciation extended much further west. The isolation of D. hrimhyo- 

 rum in Arkansas and the fragmentary range of D. fusca in Indiana 

 and Illinois led me to this belief when writing my revision of the genus, 

 though at the time I did not expect so startling a corroboration. 



59. Desmognathus fusca auriculata (Holbrook). 



N. C: Beaufort, 1,168 (9); 4,657; 4,658; New Berne, 1,884.— Fla.; Jack- 

 sonville, 1,070 (3).— Ala.: Mobile, 2,783; 4,746; 4,747. 



60. Desmognathus brimleyorum Stejneger. 



Ark.: Hot Springs, 2,598 (2 paraiypes); 2,537; 2,784 (2); Little Rock, 

 3,142; 4,547-4,550 (4). 



61. Desmognathus ochrophaea ochrophaea Cope. 



Loc. ? 4,471-4,474 (4).— N. Y.: Berkshire, 4,591-4,593 (3); Ithaca, 3,158; 

 3,163; 4,525-4,527* (3).— Pa.: Gold, 4,475-4,480 (6). 



62. Desmognathus ochrophaea carolinensis Dunn. 



N. C: Black Mountains, 1,162 (3); Blantyre, 2,631; Macon County, Bald 

 Mountain, 2,543; Saluda, 4,481.— Tenn.: Unaka Springs, 4,482.— 

 Ga., 212,' 4,594-4,599 (6). 



63. Stereochilus margin atus (Hallowell). 

 N. C: Lake Ellis, 2,541 ; New Berne, 4,742. 



New Berne is the most northerly, and I believe the third recorded 

 locality for this rare species. 



64. Typhlotriton spelaeus Stejneger, 



Mo.: Stone County, 3,141; Stone County, Marble Cave, 2,781 (2); 2,873- 

 2,880 (8); Stone Comity, Reed's Spring, 3,485 (larva); Wright County, 

 Davis Cave, 2,554 (2 larvae). 



This species seems closest of all to the free-tongued species of the 

 Plethodontidae. The tongue is a great deal freer than in any other
