12 peesident's addeess. 



mals new to the district have been found ; one, however, the black 

 Rat, which was thought to be extinct, has been noticed as still 

 occurring in it. Four species of Birds, new to the two counties, 

 are enumerated; namely, the Thrush Nightingale (Sylvia turdoides 

 major J, the Fulmar (Procellaria glacialis, Linn.), the Gadwall 

 (Anas Strepera, Linn.), and the "White Stork {Ciconia a?6a,Linn.) ; 

 the first of these is new also to Britain. 



One Reptile, new to the district, the Red Viper (Coluber 

 Chersea) has been recorded. Of Fishes, the Black Fish (Centro- 

 lophus Pompilius) is new to our coasts. The Ribbon Fish (Gym- 

 netrusBanksii) was at first thought to be new, but further research 

 has shown that it is occasionally found. The short Sun Fish 

 ( Orthragoriscus Mola), though not new, is comparatively rare; 

 but has been, with the Ribbon Fish, newly described. 



In the Molluscan Sub-Kingdom, Messrs. Alder and Hancock re- 

 port sixty species, of which nineteen are altogether new to science, 

 seven, new to Great Britain, and thirty -four new to our district.

 Insects so large, and yet so indeterminate, owing partly to the 

 absence of previous lists, that I am compelled to omit this class 

 altogether in the enumeration. Of Crustacea, two species, new 

 to the district, have been pointed out by Mr. Richard Howse, jun. ; 

 and Mr. Albany Hancock has done us the honour of introducing 

 to our notice, an entirely new order of Articulata, belonging to the 

 class Cirripedia ; the order he has named Cryptosomata, and the 

 new animal, the only representative of the only genus, Alcippe 

 Lampas. 



In the Radiate Sub-Kingdom, Messrs. Alder and Hancock report 

 the acquision of six species new to science, and one new to Durham 

 and Northumberland. Of Sponges, according to Mr. Albany 

 Hancock, four species altogether new, and one new to the coasts 

 of our two counties, have been discovered; they belong to the 

 singular and almost altogether new group of " boring sponges." 



Vegetable Kingdom. — Our indefatigable Secretary, Mr. Storey,
