Bate with his own Amphitlioe IMorina ; both are by Boeok made synonyms of Ratbke's 

 Amplntho'6 podoceroides. All three should in my opinion fall into the synonymy of 

 Amphitlioe ruhricata, Montagu. The description of Gammanis duMus is quoted by Bate 

 and Westwood, vol. i. jsp. .397-398. It seems likely to remain in the doubt in which both 

 they and the author of the species left it. The description of the antcnnsg points to some 

 species of Calliopius or Amphithopsis, but the two " papillaj," which seem to be meant for 

 the telson, would be inconsistent with these genera. Gammarus nolens is likewise left 

 among the doubtful species by Bate and Westwood, vol. ii. p. 19. It had been, without 

 sufficient reason, re-named by White Typhis nolens and subsequently Anonijx (?) nolens. 

 It is as likely to be the Hyale nilssonii of Rathke as any other species that I am acquainted 

 with, but the description is not sufficiently definite to entitle it to displace Kathke's specific

Zenker, 1832, says that this author described the circuit of the blood and of vegetable sap more 

 as a poet than a naturalist, maintaining that not only in the sap of plants, but also in the 

 blood of animals monads are found, and that all trunks are zoophytes, inhabited by 

 hamadryads. He quotes from him the following pas-sages relating to Gammarus pule.r : — 



" Pag. 56 : Globulos sanguinis, ait, recto pergere tramite et hoc {i.e. banc directionem) ipsis 

 utpote animalculis prudentibus (" sinnigen thieren ") esse innatum. 



" Pag. 69 : Succos Gamniari Pulicis effusos in 7n(mades atque in globulos cam.pannliformes majores 

 distribui, qui inter se plures haberent monades, idem auctor narrat. 



" Pag. 70 legitur : Gammari P. corpore disrupto globuli sued duplicis generis profmmt. 

 Majores campanulati leiitius moventur, diversas versus dirediones, minores monades velociter 

 diversas sequuntii/r regiones et varia velocitate, et sic plures fluminis instar ! 



■" Pag. 74. denique prodit auctor noster, sihi ex Gammari extrcmitate (pede) abscissa in massa 

 musculari (?) coxa; acervum globulorum separatoritm et vorticc eonoolutatornm videre 

 contigisse, ciijus rei libenter ipsi fidem habeamus, nam si phantasias lusibus obtemperemus, 

 tunc omnia cernere possumus, quae iraaginatio nobis proponat." 



Zenker's last observation would apply to bis own ternary and quinary distribution of the parts 

 of Gammarus pulex.
