REPORT ON THE AMPHIPODA. 349 



Under Cerapiis Say, he thus describes " C. latimanus Gr. n. sp. Jahresbericht d. Schles. 

 Gesellsch. fiir 1863. Zeigt grosse Uebereinstimmung mit dem Mainnchen von C. abditus 

 Templet. (Spence Bate Brit. Sessil-eyed Crust. I. p. 455. Fig.), aber die Hand des zweiten 

 Fusspaares ist iiber halb so breit als das vorhergehende Glicd, ihr Unterrand nur mit 1 

 zwischen die beideu vorderen Zacken desselben eingreifenden Vorsprunge verseheu, sonst 

 glatt uiid die flach sichelformig gestaltete Klaue vom Grunde an allmiilig verjiingt zulaufend. 

 Die Liinge von C, abditus wird auf etwa 1 1 Lin. angegeben, unser Cerapus misst 5 mill. ; 

 bei Neresine gefunden." Under Caprella Lam., he describes " C. inermis Gr. n. sp. ohne 

 alls Eiickenstacheln und Hoker, der oben gewolbte Kopf mit dem ersten Segment zusammen 

 beinahe ebenso lang als das zweite, die oberen Antennen etwa nur \ kurzer als der Korper ; 

 ahnelt der C. I'obusfa Dana, doch ist der Unterrand der langlich ovalen Hand des zweiten 

 Fusspaares zahnlos ; die iihnlich gestaltete Hand des ersten ist wenig kleiner, das letzte 

 Fusspaar war nicht erhalten. Lange etwas iiber 3 mill.; Lussin piccolo." Mayer thinks 

 that this may just possibly be the young of Caprdla aautifrons, Latreille.

In this translation of the celebrated work, Fiir Darwin, are figured Melita exilii, n. sp., " Orchestia 

 Darwinii," n. sp., two forms of the chelte of the male of this species, portions of the penulti- 

 mate perajopods of " Melita Messalina " and " Melita iiuatiabilis," an embryo of a 

 Corophium, portions of the legs of " Hyperia Martinezii," n. sp., and the second gnathopod 

 of the male and of the female of " Orchestia Tuniratinga," while mention is made of Coro- 

 phium dentatum, n. sp., without either figures or description, and of " Orchestia Tucurauna," 

 n. sp., which is apparently the same as " Orchestia Tucuratinga." 



A protest may be entered against the inconvenient course of publishing new species at various 

 points of a highly argumentative essay, especially when the descriptions are almost of 

 necessity confined to those isolated characters with which the argument happens to be con- 

 cerned. 



Fritz MUHer has found the secondary flagellum on the upper antennse " in species of the genera 

 Leucothoe, Cyrtophium, and Amphilochus, in which genera it was missed by Savigny, Dana, 

 and Spence Bate." "A species proved by the form of the epimera (coxx Sp. Bate) of the 

 caudal feet (uropoda Westw.), etc., to be a true Amphithoe possesses it." " In many .species 

 of Cerapus it is reduced to a scarcely perceptible rudiment." " It is sometimes present in 

 youth and disappears (although perhaps not without leaving some trace) at maturity, as was 

 found by Sjjence Bate to be the case in Acanthonotus Owenii and Atylus carinaius, and I
