spine and is relieved by the pale olive-grej or yellowish colour of 

 the dorsal area ; the sides are darlcer, brown, with longitudinal 

 series of small dark brown spots ; head with the usual black 

 markings ; lips uniform yellowish ; lower parts black, spotted with 

 white, or grey, spotted or chequered with black and white ; tail 

 but rarely tipped with yellow ; throat yellowish white in both 

 sexes. 



Herr L. von Kirchroth, of Modlhig, who has collected large 

 numbers of this Yiper, kindly supplies me with the following 

 information respecting its occurrence near Vienna : — 



This Viper is distributed from Laxenburg westwards as far 

 as the eastern slope of the Anuinger Hills, southwards as far 

 as Traiskirchen and Tribuswinkel. Its chief habitat is in the 

 immediate vicinity of Laxenburg, where it is found in extraor- 

 dinary numbers. The intendant of the Imperial Castle pays a 

 premium for the destruction of Vipers, and in the course of last 

 year more than 1000 specimens were brought to him. These 

 snakes are found principally, though not exclusively, in the marshy 

 meadows around the park ; but few occur in the park itself. They 

 feed chiefly on Lacerta agllis and also on mice. The largest mala 

 examined by Herr v. Kirchroth measured 410 mJllim., the largest 

 female 450.

[The Society published last year (P. Z. S. 1892, p. 196) a memoir 

 by Hofrath C. Brunner v. Wattenwyl and Professor J. Eedten- 

 bacher on the Orthoptera of the island of St. Vincent which those 

 distinguished entomologists had been so good as to prepare at the 

 request of the Joint Committee appointed by the Royal Society 

 and the British Association to investigate the Fauna and Flora 

 of the West Indian Islands. 



I have now, on behalf of the same Committee, the pleasure of 

 offering to the Society a paper by Herr Brunner v. Wattenwyl 

 enumerating the Orthoptera of the neighbouring island of Grenada. 

 Fifty-five species have been obtained there, nineteen of which were 

 not met with in St. Vincent, eight of the number being described as 

 new species. Of this order St. Vincent, on the other hand, possesses 

 62 species, 27 of which have not been found in Grenada. 



It would at first sight appear from these facts that there is a
