TIm' head is rather small an*l iiarri>\v. The proportion of eyes, eU\, 

 iiiiKih as in S. ruUvr. The snout is, howevei', more ainiiptly truneatetl, 

 sliowin^" the nostrils on eaeh side at the eorner formed with the side «»f 

 the head, and with an indistinet rid<{(> riiiinin;;' down to the Jaw as in 

 a. in>ri>liifriti<us, hut less marketl. Tin' top of the head is more convex, 

 and not llattened between the eyes. The toii;;ue is a eiicular pediin 

 eulatetl disk. Tiie teeth curve j;ently fiv.ni behind the inner nares to 

 the paraspheiioid bone, not at an an;L;le, and the two lou;4itudind series 

 are so close colli iniUMisly as to c.\liil>it no furrow (»f sepaiatiun. and very 

 little of on(M)e!iiiid. Tlie palatine portion does not extend outwards 

 licyond the outer border of the inner nostrils. 



[•idfessor l»aird described this species in ISI!> from a siiijile adult 

 >p(-ciiueii can^iht in the South Mountain, near Carlisle, I'a. Siiicti 

 tlii'ii several others iVoin tlillerent localities have been oiitaiiied, and 

 after the renewed examinali(ui of many speciineiis of S. nilnr I am 

 silislied of its distinction as a subspecies. The cohMMti'Ui is always 

 appr«'ciably dillerent in the very . sk iris without loiiLjitudinal bar of 

 .Moiitaims, compared with the brassy yellow iris with longitudinal dark 

 bind' Jtulter. The ;iioiiiid color above is iiuiforinly and continuously 

 Uiiiwnishsalmon, much as in (i. jxirjiliifrilicHs, with a few well defined 

 circular spots. In IJuin'r where the ground cohu" has become dark I'cmI- 

 dish brown, it is alw.iys mottled with Milliter, ami the larger and more 

 iiiim -rors dark spots are iikuc obsolete in their outline. 



Tiie Iliad of Moiitaiius isnarrower and much more arched tr.iiisv'Msely. 

 The snout is more truncate. The two series of teeth on each side the 

 jtai.isphenoid bone come closer, .so as to be almost in contact, without 

 I lie interval of S. ndnr. 



Till' body and tail are more slender and elon<;ated; the latter propor- 

 ,icn.i!ly consiih'rably lon-'er. Thereare 1»» costal tiirrows, exdudiii:.; an 

 axillir one, instead of lo, as in iS'. riilnr. 



Tliere are Iti distinct costal j;roo\('s, excludin;;' any in the axilla. 

 The tail shows similar furrows at lirst, but they soiui become indistinct. 

 It is (piadrate at the base, then jjiadiially becomes more and more com- 

 press, -d, with a sharp ridj-e towards the end, as in S. ndirr. lis len.i;th 

 is n.'aily equal to the distance from the s • it to the ;;roiii. 



Tlie limbs are not appreciably ditVi'ient from what has been destaibed
