REPORT ON THE AMPHIPODA. 1620 



1872. BoECK, A. 



Bidrag til Californiens Amphipodc fauna. (See p. 410.) 



A separate copy of this paper lent me by a friend was devoid of the illustrative plate, which my 

 friend assured me had never been published. The volume of the " Forhandliuger i Viden- 

 skabs-Selskabet i Christiania Aar 1871. Med 3 lithographerede Plader," containing Boeck's 

 paper, possessed three plates as promised on the title-page, but none of the three had 

 anything to do with the species which Boeck describes. Mayer, Die Caprelliden, p. 12, also 

 says that he is indebted to G. 0. Sars for the information that the plate in question was 

 never printed. In May, however, of this year to my surprise I was able to obtain from 

 Oswald Weigel in Leipzic a separate copy of the paper with the missing plate. 



The figures confirm the view taken in my account of Caprella seaura, Templeton, p. 1267, that 

 the Caprella californica described by Boeck is one of the synonyms of that species. The 

 rounded apex of the hand in the second gnathopods is rather conspicuously produced in 

 Boeck's figure, and the tooth on the inner margin of the finger near its hinge has an appear- 

 ance slightly differing from what is found in other figures and specimens which I have 

 regarded as belonging to Templeton's species, but these small variations are of no great 

 weight in themselves, and may, I think, be in part attributed to the accidental condition of 

 the specimen figured. 



The species named Caprella verrucosa, which Mayer thought might possibly be the young of 

 Caprella acanthi/era, Leach, is shown by the figures to come nearer to one or other of the 

 forms that have received the specific name tuberculata. It is distinguished from Caprella 

 acanthi/era by the very prominent frontal tooth or horn, and from all other species of Caprella 

 by the considerable size of the process of the hand in the second gnathopods of the male, a 

 deep cavity being formed between this process and the distal part of the hind margin which 

 is slightly concave. Boeck himself says that the species " is so peculiar by its short 

 antenna? and its body beset with large, finely tuberculated warts, and lastly by the slight 

 difference in the structure of the body in the two sexes, that it cannot be confused with 

 any other described species."

The preface is dated " Prag im Juli 1871." The account of the Amphipoda is given on pp. 264, 

 265. It contains the following descriptions : — 



" Gatt. Gammarus. Die oberen langeren Fiihler tragen an der Spitze ihren 3gliedrigen Stieles, 

 neben der langen Geissel, einen kurzen 5gliedrigen Faden ; die beiden vorderen Fusspaare 

 in beiden Geschlechtern Greiffiisse, deren hakiges Endglied sich gegen das verdickte 

 Fussblatt einschlagt. Die Afterfiisse der beiden letzten Hinterleibsglieder und die beiden 

 Endanhange des Schwanzes sind gabelige Spriugstiele." 



" Gammarus pulex, Fabr. [Fig. 99]. Das vorletzte Glied des ersten Fusspaares ist birnformig 

 und nach vorne in eine kurze Spitze ausgezogen. Die Augen rund, die unteren Fiihler sind 

 mit kurzen Haaren versehen. Jedes der 3 hintersten Leibessegmente hat am Hinterrande 

 3 Borstenbiischeln, von denen die seitlichen zu 2-3 Borsten zu enthalten pflegen. Die 

 Farbe ist gelblich griin oder braunlich. Lange 10-15 mm. Leben in reinen Quellen und
