436 NOTES. 



snakes. My foot was raised, and not more than two feet from the spot, 

 when I discovered the venomous brood just below me. 



Nate 58, page 148. The following list of marine creatures living in 

 fresh water is not complete. 



Cmleiiterata. 

 Cordijhiphora lacustns (see text). 



JBryozoa. 



Memhranijjnra bengalensis (Stoliczka, Proo. Asiat. Soe. Bciig. July 

 1878). 



Vietorella 2>avida (Kent, QtiaH. Journ. Micro. Soc. 1870). 



A Flmtra of a closely allied species in a fresh- water tank at Nagpoor, 

 on the shells of Palitdiiia bengalensis and on water plants (Jl««. Mag. 

 Xat. Hist., ser. .S, vol. i. p. 1C8). 



Annelida. 



Kereis and JVcmcrtes of xarious kinds were found by Tscherniawsky 

 in a lake in Mingrelia of which the waters are drinkable. ManayunTuja, 

 a Cephalobranchiate discovered by Leidy in fresh water at Philadelphia. 



Aiihrojyoda. 



The number living in fresh water is extraordinarily great ; I will 

 here mention onlj' the most imjjortant, and refer the reader to the great 

 work of Ed. von Martens. 



Species of Balanvsm Lake Palfeotoma, according to Tscherniawsky. 



Cgprix salina and CypTidopns acnleata in quite fresh water, accord- 

 ing to Brady {Xiit. Hist. Trans. Northumberland and Durham, vol. ii. 

 part i. p. 121). 



Bnjjyrus, sp. div. ? Besides those in the Philippines (see text) 

 species occur in India ; and in various museums, as in Munich, I have 

 seen them with a fresh-water Palsemon, P. indicus. To my knowledge 

 they have not yet been described. 



A species of Penella, according to Peters, lives on a Gohiiis in pure 

 fresh water in the Laguna de Bay at Manila. 



The marine forms which now are fovrnd at the bottom of the 

 Swedish and Norwegian lakes are of the highest interest : My.Hs relicta 

 (Loven) is still living as 3Iysis ondata in the sea near Greenland ; 

 Pontoj>07xia affinislives in the Baltic and in northern fresh-water lakes. 

 Both species have lately been found by Alleyne, Nicholson, and Smith, 

 in the great North American Lakes Ontario, .Superior, and Michigan (see 

 SiUiman's Journ. ser. 3, vol. v. 187:i, p. 387 ; vol. ii. 1871, pp. 373, Hi ; 

 vol. vii. 1874, p. 161. 



I may add to the list o£ fresh-water crabs given by Martens Varuna
