1873.] F. Stoliczka — Two neio species of Indian Landshells. 1G9 



this large scale covers a small opening, in which internally a rather 

 strong muscle terminates ; the muscle is most probably emissible and retrac- 

 tile at the will of the animal. 



All other characters are common to both sexes. The upper labial is 

 separated from the rostral by a distinct groove. The shields are dark brown, 

 almost blackish, with paler edges ; paler below. The shields on the head' 

 are yellowish^and there are occasionally yellowish spots on the chin and 

 throat, or on the lower side of the tail. 



As compared with Typliloscincus Martensii, Peters, the snout of the 

 Nicobar species is narrower, the head posteriorly broader, the eyes, although 

 covered by skin, distinctly traceable, all points to which Steindachner 

 drew attention when comparing the two, but the shields of the head, the 

 number of scales round the body and on the tail are in both species quite 

 the same. There is in T. Martensii also an enlarged scale above the anal 

 edge, but it is nearer to it than in the Nicobar species. Still, if it were not 

 for Peters' distinct statement, that out of three specimens of T. Martensii 

 two are males, and one a female, both without any trace of extremities, 

 I should have considered the specific distinction of the D. Nicoharicus 

 from T. Martensii somewhat doubtful. The coincidence is certainly re- 

 markable. 



Dihamus was characterized by Dumeril and Bibron (Erpet. gen. v. 

 p. 833) from two New-Guinean specimens, sent to them by Prof. Schlegel. 

 Both specimens were apparently males, but Schlegel* says that these only 

 possess a pair of posterior extremities, the females having none. And this 

 is strictly in accordance with the observation made on the two Nicobar 

 specimens. 



Desceiptions of two new species of Indian Landshells, 

 hy Dk. F. Stoliczka. 



[Received 7th May, 1873.] 



The following descriptions have been drawn up with the view of 

 supplementing the figures of them which are to be given by Mr. Theobald in 

 the ' Conchologia Indica.' The first species is from the Shan-states, and was 

 collected, several years ago, by Mr. Fedden ; and the second was given to 

 me by Mr. Foote who obtained it in the cotton soil district near Bolgaom, 

 when on his geological tour.
