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. 



JVffte 5S, page US. The following list of marine creatures living in 

 fresh water is not complete. 



Cteleiiterata, 

 Cordj/lojihora laouMris (see text). 



Bryozoa. 



Menibranipora ieiigaleiisis (Stoliczka, Proc. Asiat. Sob. Beng. July 

 1878). 



Yietorella pamida (Kent, QnaH. J<nm-n. Micro. Soc. 1870). 



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

 on the shells of Pahidiita bengalensis and on water plants {Ann. Mag. 

 Nat. Hut., ser. 3, vol. i. p. 168). 



Annelida. 

 Nerds and NcmeHes of various kinds were found by Tscherniawsky 

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

 a Cephalobranchiate discovered by Leidym fresh water at Philadelphia. 



ArtJiropoda. 



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

 here mention only the most important, and refer the reader to the great 

 work of Ed. von Martens. 



Species of Balanus in Lake Palseotoma, according to Tscherniawsky. 



Cypris saWna and Oypridopns acnleata in quite fresh water, accord- 

 ing to Brady (JVai. Hist. Trans. Northumberland and Durham, vol. ii. 

 part i. p. 121). 



Bopyrus, sp. div. 1 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 Pentlla, according to Peters, lives on a Goiivs in pure 

 fresh water in the Laguna de Bay at Manila. 



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

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

 (Lov^n) is still living as Mysi,i oculata in the sea near Greenland ; 

 Pontoporeia affinisWves 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 

 SilUman's Journ. ser. 3, vol. v. 1873, p. 387 ; vol. ii. 1871, pp. 373, 448 j 

 vol. vii. 1874, p. 161. 



I may add to the list of fresh-water crabs given by Martens Varvna
