REPOET ON THE AMPHIPODA, 37 



postrenal paris postico acuta, lamina dimidiato-subrotunda, Integra, magna, quatuor lincas 

 longa. Cauda foliata, foliolo unico brevi bifido : Lacinix lanceolatce, acutse. Neusteri 

 duodecim, duplicati, subulati, pilis longis ciliati, posteriores retrorsum porreoti. OJm. 

 Specimina magnitudine variant, unoialia et biuncialia crant." This is now the type of the 

 genus Stegoeephalus, Kr0yer, 1842. 



"Cancer niigax, macrourus, articularis, pedibus quatuordecim simplicibus, laminis femorum sex 

 posteriorum dilatatis subrotundo-cordatis. Tab. xii. Fig. 2. This animal, which has not before 

 been described, should be inserted in the SyfUenia Natures, near Cancer Pulex ; it was taken 

 in the trawl near Moffen Island. Description. Insectum oblongum, compressum, dorso 

 rotundatum, glabrum, sesquiunciale, articulis quatuordecim compositum, quorum primus 

 capitis est, septem thoraoem mentiuntur, et sex caudam efficiunt. Capitis clypeus siuu 

 obtuse antice pro antennis emarginatus. Antcnnx quatuor, subulatae, multiarticulatae ; 

 superiores corpore sextuplo breviores, bifidse ; articulo baseos communi, magno ; Eumnliis 

 interior extsriori duplo brevior. Inferiores simplices, superioribus duplo longiores. Pedes 

 quatuordecim, simplices, ungiiiculati, unguibus parum incurvis. Femora sex posteriora postice 

 aucta. Lamina foliacea, subrotundo-cordata, dimidiata, margine Integra, magna, (tres lineas 

 longa). Ca/(f?a apice foliata. Folio/is duobus, oblongis, obtusis, parvis. iVe^wferi duodecim, 

 duplicati, Kneari-lanceolati, posteriores retrorsum i^orrecti, ut facile pro appendicibus caudaa 

 sumantur." Kr0yer, Nat. Tidsskr. 2 Pi. i. p. 578 (1844), mixes up Cancer amptdla, Phipps, 

 and "Cancer nugax, Phij)ps. 11" with his own Anonyx lagena and Anonyx appendiculusus 

 under the title Anonyx ampidla, Phipps. Cancer ampidla, as already stated, belongs to 

 Stegoeephalus. Cancer nugax, Phipps, is almost beyond doubt the same as Anonyx lagena, 

 Kr0yer, and accordingly E. J. Miers, with good reason, gives precedence to the specific name 

 nugax. 



Of his third Amphipod species, Phipps only says: "Cancer Pidex, Linn. Syst.Naf. p. 105-5. 81. 

 Taken up in the trawl along with the former." 



1774. Steller, Georg Wilhelm, bom 1709, died 1746.

 Sitten, Nahmen, Lebensart und Verschiedenen Gewolinheiten berausgegeben von

Mayer, Caprelliden, p. 4, remarks, "Pallas, dessen SpicUegia zoologica ich nur aus der Ueber- 

 setzung von Baldinger kenne, fasst 1767 die ihm bekannter Amphipoden unter dem 

 Namen Oniscus zusammen und beschreibt als 0. Scolopendroides (Eohrpolypenlaus oder 

 kleinste Afterassel) eineu halbdurchsigtigen, gelben, nach der Abbildung zur heutigen 

 Gattung Caprella gehorigen Krebs, den Steller schon als Pedicidus marinus m Kamtschatka 

 beobachtet haben solle." He appends a note to explain that he has not himself had an 

 opportunity of examining Steller's work on Kamtschatka. The only passage in it at all 

 applicable, that I can find, is on page 199, where, in a note, Steller says, " An der See soil 

 sich ein Insect befinden, wie eine Laus, welches durch die Poros der Haut in das FIcisch 

 und immer welter kriechet." This causes horrible pam, and can only be got rid of by 

 cutting it out. Steller had not himself seen it, but promises to look out for a chance of 

 doing so. His account of it so far is little suitable to Capi-ella. In the note on Pallas, 

 1772, it will be seen that he ascribes to Steller the credit of having accurately described 

 Oniscus scolopendroides observed by him in Kamtschatka, but it is the description " hujus 

 insectuli marini," not of a pediculus marinus, that he has left in his papers. See also note 

 on Tilesius, 1815.
