174 THE VOYAGE OF H.M.S. CHALLENGEE. 



size, 3-6 lines, all coincide with the position in the system which Boock has as igned to it. 

 My own drawings of Hijale {Nicea) luhhockiana, Ann. and Mag. Nat. Hist, for May 1876, 

 made years before I was acquainted with Eathke's work are in close agreement with those 

 by W. Papa on Eathke's plate v. As in the Annals for November 1879, I identified 

 Allorchestes imhricatut:, Sp. Bate, with Nicea lubhochiana of the same author, so now, after 

 seeing the strongly imbricated figure in Eathke's work, I am inclined to identify both with 

 Eathke's Hyale pontica. 



From Mr. Faxon's own observations, that in the type of AlJorehestes media, Dana, the telson is 

 cleft to the base, and that in fact the telson is probably cleft in most of the marine forms, 

 which would be the bulk of Dana's genus, I think it is unreasonable to give the name 

 AUorchesfes to species with an entire telson. But Nicea, which has been assigned to the 

 species with a double or cleft telson, cannot claim priority over Allorekestes. They are in 

 fact both synonyms of Ili/aJe. For the species with an entire telson there will then be left 

 the name Hijalella, originated by S. I. Smith in 1874. See also Note on Biandt, 1851. 



One other new Amphipod is described by Ratlike from the Crimea under the name Amphithoe 

 picta. Of this Spence Bate remarks, " I can detect no specific distinction between this 

 species and A. littorina of our own shores." Nevertheless he retains the species, giving 

 the description of it from Milne-Edwards instead of from Rathke. But INIilne-Edwards 

 describes the first and second gnathopods as " presque egales, mais assez larges," whereas 

 Eathke himself says, "Das erste und zweite Beinpaar sind gleioh lang und haben auch 

 ziemlich gleich grosse, in Verliiiltniss zum ganzen Korper aber nur kleine Hiinde," and in his 

 Latin description, " pedum duobus paribus anticis subaequalibus, chelis eorum minimis. 

 In the British species or variety, " Ampldtlwi' lifforina, Spence Bate," the size of tlie 

 gnathopods is very variable, so that Milne-Edwards' account may perhaps be unintentionally 

 accurate. Eathke found his specimens "in the bay of Balaklava, where it habitually lodges 

 under stones, and resembles Gammari in its mode of life."

The history of the Crustacea, the Eighth Class, occupies from page 154 to page 498 of this 

 volume. Of the sub-class, Crustaces maxilles, the second legion, Edriophtalmes, contains 

 the tliree Orders, Amphipodes, Loemipodes, Isopodes. At p. 256 the editor remarks that 

 most authors have wrongly assigned as a character to the Isopoda, the absence of a palpiforni 

 appendage from the mandibles; he divides the Isopoda into three families, Cloportidiens, 

 Cymothoadiens, Idotcidiens, in the second of which he places Typhis. However, at p. 285, 

 a note signed "E" states that "les Typhis appartiennent a I'ordre des Amphipodes, et a 

 la famille des Hyperidiens," and refers to the " article Typhis du Dictionnaire classique 

 d'histoire naturelle, t. 16, p. 449." "Espece. 1. Typhis ovoide. Ti/plds ovoides. Eisso. 

 Hist. nat. des crust, p. 122. pi. 2. fig. 9," is followed by references to Desmarest and 

 Latreille and to "le iijpjhis fen-us" and "le typlns repax" [rapax], both of Milne-Edwards, 

 but so given as to appear more like synonyms of ovoides, than separate species for whicli 

 they are no doubt intended.
