472 THE VOYAGE OF H.M.S. CHALLENGER. 



caudal appendages are attached. The five pairs of ambulatory legs are long and slender, 

 and the three pairs of ' swimmerets ' are normal. The eggs are large and few in number ; 

 some of those observed contained embryos in which nearly all the appendages were de- 

 veloped, showing that the young undergo no metamorphosis. 



"Dr. von Willemoes-Suhm, who has carefully described this singular form, has proposed to 

 establish for the genus a family Ctstosomid^, holding a place intermediate between the 

 Ttphid^ and the Phronomid.«." 



A casual allusion to Amphipods occurs on p. 388.

The notices of Amphipoda in this work are as follows : — Introd., p. vi. " The order Amphipoda 

 has one representative in the Upper Silurian (the Necrogammarus Salweyi, H. Woodw.) ; it is 

 represented by Gampsonux in the coal of Eheuish Prussia, and by the genus Proscqjonisms 

 in the Permian of Durham. Other (Secondary) species occur in Bavaria, etc. The living 

 genera of Amphipoda are abundant, both marine and freshwater ; and some species are even 

 terrestrial in their habits." 



The table of genera and species, etc., on p. viii., assigns but one genus and one species to the 

 British fossil Amphipoda.

Sijniirella piolonica, a new genus and species, is here introduced, but not described, since the 

 account of its circulation can scarcely stand either for generic or specific description. The 

 name Synurella was afterwards, with perhaps unnecessary purism, changed to Goplana. 

 The change indeed would have scarcely been legitimate, had Synurella at its first introduc- 

 tion been attended by sufficient description to give it a status in scientific nomenclature. 

 The interesting details in regard to the heart, etc., were subsequently repeated with 

 improvements. Eeference is made to " Callisoma BranicJcii," earlier described, and to 

 " Hyale Jehlii " described subsequently.
