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



must take precedence. The Brit. Mus. Catal. gives tliem as two separate species, thougli 

 Kr0yer's descriptions are identical, so far as the shorter one extends. 



Remarks on the habits of animals belonging to the genera Anonyx and Opis are quoted from 

 Holb0U. These are followed by an account of Microclieles armata, supposed to be a new 

 species and type of a new genus Microclieles, thus defined : — 



" Primum secundumque pedum thoradcorum par exilia, linearia, chelis armata minutissimis. 

 Mandihula parva, apice bifurcate, non vero dentato ; palpo triarticulato ; tuberculo molari 

 proprio nullo, ante palpum vero corpore instructa claviformi, dentato. Lahinui infarius 

 quatuor constans laminis fere sequalibus, cornubusque lateralibus sat maguis. Pedis 

 maxillares laminis maxillaribus magnis, palpo brevi, triarticulato (ungve destituto). Einmera, 

 magna ; paria quatuor anteriora inferius in angulum acutum producta. Pedes abdominis 

 saltatorii elongati, gracilesque. Anicnnx forma ferme vulgari, superiores flagello appeii- 

 diculari destitutse." 



The species, Microclieles armata, is figured in the Voy. en Scand., pi. 11 B, fig. 2, a-v. It was 

 subsequently identified by Liljeborg with the earlier fyhimedia ohesa of Rathke, so that 

 both the generic and specific names used by Ivr0yer take rank as synonyms. 



Amphitlioe alhomaculata, here described as new, is by Boeck identified with Ampliiilio'e podo- 

 ceroides, Rathke, and is therefore probably not more than a colour variety of Amphitlwe 

 rubricata, Montagu. 



Next, "Amphitlioe Edwardsii" is described, under the name which Owen gave to the " Talitrus 

 Edvardsii " of Sabine, which is identical with Oniscus aculeatus, Lepechin. See Note on 

 Lepechin, 1780. 



Lastly, Acanthonotus trieuspis, n. s., is described, pages 115-123. This species was afterwards 

 by Boeck made the type of his genus Cleipindes, The species included in this continuation 

 are all figured in the Voy. en Scand. For the benefit of any one unacquainted with the 

 alphabetical order used in the Scandinavian languages, it may be pointed out that in the 

 Indices to Kr0yer's papers, the diphthong as and the symbol o or follow the letter z. 



1846? Kr0YER, Henrik. 



Voyages de la commission scientifique du Nord ; eu Scandinavie, en Laponie, 



au Spitzberg et anx Fero, pendant les annees 1838-1840, sur la corvette la Eecherche, 



commandee par M. Fabvre. Publics par ordre du Roi sous la direction de M. Paul 



Gaimard. 17 vols. Paris, 1842-1848. 8°. Atlas, fol. undated. 



The reputed date of publication is 1846, for the Atlas of Crustaces. It consists of plates for 

 which no text was ever published, and is attributed by repute to Kr0yer. W. Thomson, 

 in 1847, refers to the plates as Krpyer's. Brandt, in 1851, compliments Kr0yer on figures 

 ot Anonyx in this Atlas, " Livr. 37-41 auf. PI. 13-18 meisterhaft von ihm dargestellt." 

 The beautiful figures agree with the elaborate descriptions which Kr0yer gave from time to time 

 in his Naturhistorisk Tidsskrift, but the plates which appeai'ed occasionally in that magazine 

 have none of the artistic pretensions of those in the Voyages. As Kr0yer's own name nowheie 

 appears in the present work, it may be presumed that he was not the draughtsman, but the 

 editor, who supplied the dissections and supervised the delineations. The Amphipoda figured 

 are named as follows : — PI. 10. Ampliitoe edioarddi. Sab. ; Ampliitoe pulcliella, Kr. sp. n.
