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



Nat., ed. xii., 1767, gives not linearis but atomos as Easter's species, defined as "Macrourus 

 linearis artionliii'is, manibus adactylis, pedibus undecim." Mayer remarks that Easter has 

 given to tbe hand of the second gnatliopod an armature of five teeth. In my copy there are 

 only four. He also observes that Easter figures as the tailpiece a protruding portion of

the intestinal canal. Probably the eleventh (!) leg in Linnaeus' account is due to this 

 supposed tail. The figures from Plate IV., which " I. Ehodius ad vivum pinxit," are 

 reproduced in the accompanying woodcuts. Figures A, B, are the natural size ; C, the 

 enlargement of B ; " a, Deszelfs Antennre. h, Eerste paar pooten ; " " g, Zyn Staartje en 

 Anus."

(3n p. 55, Squilla mantis, Amhoinensis, is thus described, " Hsec species, ex AmboLna missa, 

 plerumque ad squillas refertur, et hie locorum quoque inter illas reperitur ; licet multo 

 minor sit. Dorsum qjus minime scutatum est ; sed testa superior h duodenis constat 

 articulis, carnem continentibus. Barba, itidem geniculata, binos protendit pilos acuminates 

 binosque alios quasi pennaruni semulos, tandemque duos adhuc breviores. C-iEterum et 

 antici pedes gemini magnis instructi sunt forcipibus spinosis ; dum pedes reliqui in ungues 

 desinunt, exceptis posticis, utpote qui longis admodum uncis terminantur. Pinnatse locum 

 caudfe molliculi quidam aculei supplent." This is figured on pi. xxi. fig. 11, and has since 

 been called Seba innominata. Boeck supposes that fig. 12 on the same plate is taken from 

 a defective Amphipod, but the description is conclusive against this, as it says among 

 other things, "longiusculi duo tubuli, subcurvi, oculos in fine sue sustinent." The stalked 

 eyes are also figured. The animal in question, which Seba names Squilla mantis, Amhoinensis 

 maxima, is, he says, called Kamharetto by the Italians.

In an edition of the Systema NaturiB, dated Halse Magdebvrgicas, MDdbLX. (ad editionem decimam 

 reformatam Holmiensem), Cuncer is the tenth among fourteen genera of the Aptera. It is 

 here defined " Pedes utrinque VIII. ; prseter Manns 2 chelatas. Oculi II. distantes, pedun- 

 culati, elongati, mobiles. Palpi II magni, cheliferi. Cauda articulata, inermis." The
