beiuali cIreieckigL', voin ausgebogene und niit langcu steifuii \\ inipeni tlicht besetztc Lanit'lk'ii 

 ob Kiemen? Hinter ihnen und vor dem Schwanz sail ich eine andre verschieden gestaltete und 

 nur kurz gewimperte Lanielle. AuBerdem fand ich drei Paar sichelformige, lang gewimperte 

 Palpen oder KaufuBe". The two pairs of feet seem to correspond to the first pair of antennae 

 and the mandible; the organ that is assumed to be gills, is probably the maxilla, the then 

 mentioned lamella is the sixth limb and the three pairs of palps finally mentioned seem to 

 correspond to the comb and the epipodial plate of the fifth limb. The nature of the cleaning 

 limbs has obviously not been understood by this author; these appendages are called ,,ein 

 Paar cylindrischer, geringelter, mit einigen Borsten besetzter Faden"; they are compared to 

 the giUs, four of which were observed, and it is assumed that, like these, they serve .,zum Anheften 

 der Eier". (This interpretation was presumably influeneed by MlLNE Edwards, who in 184(» 

 called the seventh limb a ..patte oviiere".) According to PlllLlPPl the furca consists of only 

 one lamella. 



W. Baird, 1847, p. 23, interprets the first antenna correctly, he calls the second antenna 

 a „natatory foot", the mandible is explained as the second pair of antennae, the maxilla as 

 the ,,second pair of jaws", the fifth limb as the ,, first pair of jaws", the sixth limbs as ,, mandibles?" 

 and the seventh limb, which in the description is included between ,,the natatory foot" and the 

 maxilla, as the ,,oviferous foot". With regard to the scythe-shaped process on the first proto- 

 podite joint of the mandible, a figure of which is given, this author writes: ,,The part .... 

 is unique, but I do not know its nature or use." 



'El. GRVBE's descvi]yt\on oi Cypruiina (^=Asterupe) oblonga, 1859, shows in many respects 

 an important advance in our knowledge of these forms. This author was the first to observe 

 the rod-shaped organ in this family (as is shown on p. 164 this organ had, however, been 

 observed in other Cypridinifofmes by ^^^ Lilljerorg, 1853 and in Halocypriformes by 

 J. D. Dana, 1852); Gi^UBE remained, liowever, ignorant as to the nature of this organ. This 

 author gives drawings of the limbs which are, at least in j^arts, rather good. The first and second 

 antennae and the mandible are given their right names, the endite on the first protopodite 

 joint of the mandible is drawn attached to the base of tliis limb; it is called ,,hakenartige 

 Fortsatz", without the author's attempting to give any indication of its nature. With regard 

 to the explanation of the other limbs (TRliRE is, however, less successful. He calls the maxilla 

 ,,der sichelformige zarte Wulst . . . am Rande der Mandibelpalpe". The fifth limb is placed 

 some distance behind the sixth and is turned backwards; its epipodial apjiendage is called the 

 first maxilla, its comb the second maxilla. The sixth limb is said to correspond to ,,der Lade 

 der Mandibelpalpen" or else to belong to tiie ,, first maxilla". With regard to the seventh limb 

 this author, like A. PniLiPPi, is so far behind MiLXE El>\\ak[)S, 1840, that he did not observe 

 the nature of this organ as a limb; this appendage is called ..griffelformiger Anhang". Both 

 the lamellae of the furca were observed. C'uriouslv enough tlie gills, on the other hand, escaped 

 attention. Grube writes about these as follows, p. 334: ,,Was die vier wurstformigen hinter 

 demselben" (= T"' liml)) ,,am Rticken emporstehenden Korper bedeuten, die Philippi an seiner 

 Asterope ahljildt-t. ist iiicht luiliei' angegeben, sind es viellcicht abgeloste und dort angebackene 

 Ei('rkhim|)cn?"
