Nos. 455-456.] NOISES AND LITERATURE. 



' genus are created. Hermaphroditism is described in one case. One 

 Narcomedusa, a long known species of the Indian Ocean, is described. 

 Five species of Siphonophores were collected. The author states that 

 he could find no copy of the Mark Anniversary Vokune in London. 

 Let him apply to Henry Holt & Co., New York. 



The reptant decapods of the suborders Hippidea, Thalassindea, 

 and Scyllaridea, are treated by Borradaile. The first two groups are 

 taken between tide marks, the latter in the reefs or on sandy bottom. 

 There are enumerated two albuneids and three hippids (Remipes), 

 one axiid, a gebiid, four callianassas, two palinurids and one 

 Scyllarus. 



The Madreporaria are treated by Gardiner, who lays especial stress 

 on their variation, distinguishing vegetative, continuous, and discon- 

 tinuous or specific. This extensive paper is accompanied by well 

 executed half-tone plates from photographs of the dry corals. 



The Antipatharia are described in a few pages by P^orster Cooper. 

 They are chiefly Indian Ocean species. 



The Arachnida of the archipelagoes, treated by Pocock, raise the 

 question of their origin. " Some of the species, such as Isometrus 

 europaeus, Heteropoda regia and Uloborus geniculatus, which fre- 

 quent human dwellings, have doubtless been introduced by human 

 agency ; but it is probable that the ancestors of the majority of the 

 Spiders reached these islands on floating gossamer threads." "The 

 presence of only one species of Scorpion [Isometrus europaeus], and 

 that a form notoriously liable to dispersal by man's instrumentality, 

 suggests that, unless in very remote times, there has been no connec- 

 tion between the archipelagoes and the mainland of India .... and 

 this is further borne out by the almost complete specific identity
