THE NAUTILUS. 83 



ing along the river at Beach Haven, Augustus Remaley saw a fine 

 epecimen of blue heron evidently unable to fly. Attracted by the 

 beautiful bird's distress, he discovered that a clam or fresh water 

 mussel had closed tightly about one of the bird's toes and held it so 

 securely that it could not get away. In the bird's mouth was a 

 tmall fish N. Y. Herald, Aug. 16, 1908. 



Type of Ampulla Bolten This name, proposed in the Mu- 

 seum Boltenianum p. 110, for species of Achatina, Limicolaria and 

 Halia, evidently has precedence for some part of this assemblage. I 

 propose to restrict it to the last genus. Ampulla priamus Bolt, being 

 the type. — H. A. Pilsbry. 



The development of Littorina " The eggs of L. litorea, 



each enclosed in a hat-shaped capsule, are laid freely on the shore, 

 not aggregated together in a gelatinous mass. There are trocho- 

 sphere and veliger stages. L. lltorea lives down in the zone of La- 

 minaria and Fucus serratus. L. obiusata lives higher among Fucus 

 vesictilosus ; its larva leaves ihe egg as a veliger. L. rudis and L. 

 neritoides, which live near high-water mark, are both viviparous. 

 Thus the genus exhibits three stages in the evolution of the land 

 from marine mollusca, with the suppression of larval forms with suc- 

 cessive specialisations of habit." — M. M. Tattersall, M. Sc, in 

 The Irish Naturalist, Nov. 1908, p. 238.

The dredging operations of the "Challenger," '' Blake " and "Al- 

 batross" have made us reasonably familiar with the deep water fauna 

 of the western Atlantic, Caribbean Sea and Gulf, but hitherto prac- 

 tically nothing has been known of the deep water fauna off the west-
