hind iiiid on a line with the innor boitU'r of inner naivs, and cnrxcs in- 

 WiU'ds and bactkwards for a short tlistanci'. The parasplionoid ti'cth 

 begin ashort distance bohind their termination (witii a decided interval, 

 ho\V(r\er), and lorni in patdies, in contact aloii<j the median line. 



The body is eh)n;,'ated, the distance from snout to axillacontaincd L'ij 

 times in that to the groin. There arc twelve lateral costal grooves; the 

 posterior biliir(!ated above and anterior to the groin. I C the fin row here 

 be counted there would be thirteen grooves. The anterior is one inter- 

 s])aee distant from the axilla. 



The tail is very long, generally \\ times longer than the rest of the 

 animal. It is much compressed from the base to the much-attenuated 

 tip, but IS nowhere as high as the body. 



Tiie liud)s are nui(;h developed; the digits lengthened, narrow, linear, 

 cylindrical, tlepressed, and swollen slightly into bulbs at the ends. 

 There is no basal connecrting membraiu'. The third and fourth toes are 

 longest, the latter perha|>s longer of the two; the second and lifth are 

 nearly ecpial. Tin? first linger and toe arc very short, though not rudi- 

 mentary.

The ground color of this species is of a clear bright yellow, paler bc- 

 iH'atii, the ba<!k an«l sides irregidarly spiiidded with black specrks look- 

 ing like grains of rather coarse gun|)()wder. These are generally (but 

 not always) more lliickly crowded along the sides, sonu'times almost 

 forming a distinct spotted band on the sides of the tail; these black 

 si)ots are generally aggregated into a series of vertical baiuls. In 

 younger sjK'cimens, an<l many older ones, the sjwts above are arranged 

 in three rather irregular lim's, one me<lian and two lateral larger ones. 

 TIh' muzzle and entire under parts are immactulate. 



In old individuals there is sonu'times a suHuslon of reddish-brown 

 among tlu', spots on the sides, obsc-nring their outlines. The shade of 

 yellow varies sometimes to a reddish tinge. Sometimes the black s^iots 

 on the siib's are arranged in a Komewhat reticulated manner. 



This beautil!!! animal is not very active in its habits, and is almost 

 always found h\ rocky ground ami in lissures and caves in clitl's. I 

 have lu'ver seen it in the water. It was di'scribed by Katlnesipie from 

 a specimen from a cavern in Kentucky. Its distribution is thnuighout 

 the middle latitudes, rather rei>resenting the IS. ynttoUneatus of the far 

 Scmthern States. 



1 have recorded a specinu'ii of this speciies from Tennessee (Anierican 

 Naturalist, IS71, p. KM), in which the b;dancers were persistent, as in 

 the cirrigera form of ISi>dcrpvs hilin(ahi.s.
