Tliis species Axel Boeck (De Skand. og Arkt. Aniph. p. 52) proposed to refer to the genus 

 Crajigony.c, Sp. Bate, hut Aug. Wrzesniowski, after detailed comparison of MiiUer's descrip- 

 tion of Gammarus ambulans with his own species, decides that Midler's species must stand 

 as Goplaiia amhulans in the new genus along with Goplana polonica. The points which 

 distinguish Goplana polonica from Goplana amlndans are perhaps due rather to age than to 

 difference of species. Midler gives the following diagnosis of his species : — " Gammarus 

 ambulans, fronte inermi, oculis subrotundis, antenuis superioribus inferiores excedentibus, 

 flagello auxiliari miiiimo biarticulato instructis, dorso laevi, pedibus spuriis paris sexti 

 simplicibus, conicis, perexiguis, appendicibus caudas duabus, brevibus, cylindricis, apice 

 spinulosis. Long. 2'", anteunar. sup. O'S'"."

 Amphipodous Crustacean destructive to submarine timber-works. The Annals and 

 Magazine of Natural History. No. 128. June 1847. Vol. XIX. London, 1847, 

 pp. 361-370. Plates XIII. XIV. 



The characters of the genus, of which Philippi gave no detached summary, are tlius drawn out : 

 — " Chelura, Phil. Gen. Char. Budy not compressed. Head distinct. Superior aideniia; 

 shorter and more slender than the inferior, and consisting of a peduncular portion whicli 

 supports two unequally developed rami ; inferior anfeimm large, not divisible into a distinct 

 peduncle and ramus. Mandibles strong, palpigerous, furnished with a molar tubercle with 

 transverse ridges. First pair of maxillx strong, pyramidal, palpigerous ; second pair 

 lamelliform. 3Ia,nllan/ feet large, bearing a palpdike stem, and united at their origin so as 

 to constitute a great opercular lip covering all the other organs of the mouth. Tliora.r 

 composed of seven distinct segments with the epinier£e distinct and moderately developed. 

 First two pairs of thoracic feet didactyle, five remaining pairs terminated by a small 

 unopposable claw. First three segments of abdomen each bearing a pair of biramous 

 natatory feet, remainder of aljdomen consisting of one very large trunk supporting anteriorly 

 a pair of large foliaceous lobed appendages and a pair of cylindrical false feet, and terminated
