ZOOLOGICAL. 



Hersilia, Savigny — This genus of spiders is remarkable, 1st, for having three 

 joints in the tarsus, which is an anomalous fact in its class, and Idly, for the 

 smoothness of the claws, for the claw of every other known spider is toothed 

 or pectinated. These curious deviations from the ordinary structure are un- 

 doubtedly accompanied with corresponding peculiarities in the habits of the spe- 

 cies, but with these habits we are unacquainted. Three species are known, one 

 a native of Egypt (Cairo,) the others of India, having been sent from Bombay, 

 and the coast of Malabar Guerin, Mag. de Zoologie. 



Pleurotuchus, nov. gen Characterized at p. 142 Mr J. E. Gray informs us 



that this is synonymous with his genus Cicigna in Griffith's edition of the " Ani- 

 mal Kingdom," and with the Pteropleura of Weigmann. — Edits. 



Upupa Epops A beautiful specimen of the Hoopoe was shot near Coylton 



in Ayrshire on the 16th of October 1836 — P. W. Maclagan. 



Falco rufipes A fine mature male was shot on the Durham coast between 



South Shields and Marsden rocks, in the middle of last October. It was in com- 

 pany with another, which unfortunately escaped. The stomach was filled with 

 coleopterous insects — Albany Hancock. 



Motacilla neglecta A male specimen of this interesting species was shot a 



little west of Newcastle on the 1st of last May. It was with another, probably 

 a female ; and from the lateness of the season it is likely they might have bred 

 in the neighbourhood. When my brother was in Norway he met with several 

 individuals of this species,^but procured only one. It appears to be the common 

 bird of that part of Europe, and is so perhaps over the whole continent, the 

 neglecta being the species described by the continental writers as the flava of 

 Ray. — Albany Hancock. 



Regulus ignicapillus — An individual of this beautiful little bird was taken on 

 the rigging of a ship five miles off the Norfolk coast in the early part of last Oc- 

 tober Albany Hancock. 



Larus minutus. — A specimen of this bird, in the first plumage, was killed at 

 the mouth of the river Tyne last September. — Albany Hancock, Nov. 21, 1836. 



Hipparchia blandina. — Five specimens were captured about the 21st of Au- 

 gust 1836, at the foot of Whernside in Craven, Yorkshire, by Abraham Clap- 

 ham, Esq., a pair of which were presented by him to the museum of the Leeds 

 Phil, and Lit. Society, and one to myself. — Henry Denny. 



Luminosity of the Sea and Cholera. — From 1810 M. Surivay had observed
