upper labial only. Boiiienger, however, writes that the praeocular is 

 in contact with the second and third upper labials; this is the case 

 with the only specimen available for comparison, a specimen (M. C. Z. 

 18169) of somewhat uncertain data, being found in a bottle at Moro- 

 goro, Tanganyika Territory, after the capture of the town in 1916. 

 As the other material all occurred locally it is probable that it also 

 came from the vicinity of Morogoro. Both island snakes have 34 

 scale rows, the Morogoro snake 36, both differing from the usual 

 range of 38 to 44 scale rows. It would be interesting to know if 

 those with 38 scale rows are not really T. mucruso varius, for snakes 

 of the latter color race with 38 scale rows have been received at the 

 Museum of Comparative Zoology as T. schlegelii on more than one 

 occasion. 



TYPHLOPS MUCRUSO (Peters) 



Onychocephalus mucruso Peters, 1854, Monatsber. Akad. Wiss. Berlin, p. 621 



(Tette, Macanga). 

 Typhlops mucruso Boulenger, 1893, Cat. Snakes Brit. Mus., vol. 1, p. 46. 



The various color forms such as varius and liumho do not appear 

 to be worthy of recognition as the scale characters on which they 

 were based are now known to be common to mucruso forma typica, 

 nor are they confined to any definite geographical area. 



3 (U.S.N.M. 62891-3) Morogoro, T. T. (Loveridge) 1916-17. 

 1 (U.S.N.M. 63536) Kafue River, Rhodesia. (Raven) 1919. 



The three Morogoro snakes agree in having the nasals barely in 

 contact behind the rostral while they are Vv^ell separated in the 

 Rhodesian reptile. The eye is beneath the suture between praeocular 

 and ocular m the Rhodesian and in tv/o of the Tanganyika snakes 

 while it is beneath the ocular in No. 62891. No specific importance 

 can be attached to these variations. The Morogoro snakes have 30 

 mid-body scale rows while the Kafue River specimen has 34. Diam- 

 eter is included in the length 22 to 34 (Morogoro) and 30 (Kafue 

 River) times. All within the range of variation recognized by 

 Boulenger. Total lengths 135 to 335 m.m.

1 (U.S.N.M. 43097) Changamvre, nr. Mombasa, K. C. (Mearns) 

 1909. 



Unfortunately this specimen is rather dried, making it difficult to 

 ascertain its length and diameter with accuracy. I have previously 

 examined an example of this rare snake from Mombasa.
