Among the Antliata the definition of Pe/Jiculus is as follows : — "184. Pediculus. Os haustello 

 atque proboscide. Haudclliun retractile, recurvum. Antcnnx sahMla.ix.'" Under this genus, 

 on p. 810, though, as will be seen, with doubts, he retains the confusion which Linnwus had 

 introduced between Martens' whale-louse and Brunnich's Pycnogonum, in the following 

 entry : — " Bdleenanim. 35. P ? abdomine dilatato, muricato, rostro porrecto, subulato.

Cijdisoma neptuni, Guerin, 1842, which had anticipated Tliaumops pellucida, "WiUemoes-Suhm, 

 must obviously itself yield priority to Oniscus spinosus, Fabr., above-described.

On page 709 he describes Oniscus muricatus — " Magnitudo fere Squillas vulgaris, sed conformatio 

 quae Oniseis squilliformibus reliquis. Segmenta corporis septem, caudae tria priora 

 utrinque ad dorsum aculeo conico mucronata. Pedes 4 priores cheliferi, primi minores. 

 Cauda stylis sex terminata, quorum duo medii breviores, crassioresque. Color vivi 

 cinerascente-albidus ; siccati, cocti vel a liquore spirituoso conditi coccineus. In Angara 

 inferiore circa morticinia et quisquilias aqure injectas colHgitur copiose." He appends a 

 note that a description of this species is to be found in tlie ninth fasciculus of the Spicil. 

 Zool., p. 52, but that the figure there is not a good one, in particular the dorsal spines being 

 omitted. Its seems therefore clear that Oniscus cancellus is here for some reason renamed. 

 Herbst mentions that in the German translation of the Spicilegia Oniscus cancellus is called 

 Oniscus rmiricatus.

Under " Pou de Baleine, piediculus cdi," p. 314, will be found an account, not of Cijamus, but of a 

 Cirripede, probably Goronula diadema. It is " un animal testacee, commun dans les mers 

 du Nord." " Quand on presse avec les doigts ce coquillage encore vivant, il repand uno 

 liqueur noiratre. Sa tete ne se montre guere a decouvert ; elle est presque toujours 

 cach^e sous son enveloppe pierreuse." " Cette coquille est percco dans le milieu d'un trou 

 rond ; divisee en plusieurs cellules etroitos et profondes." Nevertheless a reference is given
