Pages 31-40 contain " Observationes de animalculis aliquot marinte aqua; innatantibus atque in 

 littoribus belgicis obviis " by Laur. Theod. Gronovius. Among other things he found, he 

 says, some very minute Crustaceans, seen by the microscope to come near to the creatures 

 which go by the name of Pedkuli ifarini, which Linnaeus mixed xnp with the Cancri, 

 though they difier from them toto cokIo. He therefore determines the name and generic 

 marks as for a new genus, thus : — " Squilla. Corjms filiforme, articulatum, longum, teres, 

 in dorso reclinatum natans. Antennx subulatre, articulatse, quatuor. Pedes pr^elongi 

 graciles quatuordecim utrinque scilicet VII, binis anterioribus paribus cheliferis. Oculi duo, 

 ad latera capitis, noa stiliformes, simplices utrinque uuicus. SQUILLA acaudata jsedibus 

 quatuordecim. Fig. 8, 9. Ccqnit rotundum antice deisressiusculum superne planum. 

 Oculi duo, sphffirici, simplicissimi, hand styliformes quemadmodum in astacis cancrisque, 

 utrinque in lateribus unions. Antennx quatuor, articulatae, subidatse, simplices, in antico 

 capite sitae, per paria dispositfe. Corpus preelongum, teres, articulorum sex, excepto capite. 

 Articulis secundo & tertio in gravidis intra pedes adhaeret prsetenuis atque utrinque convexa 

 membrana ova includens ; qualem exhibui X'/- 10- '^- ^- qui articuli respondents^. 9. litteris 

 a. b. Pedes graciles, longi, in universum quatuordecim, utrinque scilicet septem, horum 

 bina priora paria chelis sunt instructa ; reliqui vero pedes sunt subulati natatorii. Singulum 

 par est adnexum articulo. Clielse anticorum pedum sunt monodactylse, prioris paris non

 termiuat. Dum natat dorso incumbit atque velocissime ope posticorum pedum per aquas 

 transiens. Color cinereus ; Calida tempestate in obscuro lucet dum vivit. Frequentissimum 

 animal in nostro mari." A very good figure, much more accurate than the later one by 

 Slabber of his Phtisica marina, accompanies this description, which evidently applies to 

 Proto ventricosa, O. F. M.

He gives a figure, pi. x. fig. 6, of a Caprella from Ceylon, which in Boeck's opinion may be 



Caj^rella ultima, Sp. Bate. Mayer, however, finds nothing to justify a more definite 

 determination than that it is the male of some species of Caprella. Caprella ultima, Sp. 

 Bate, may itself, he thinks, be a synonym of Caprella xquilihra, Say. De lliville's figure 

 has what for a Caprella would bo a long tail, " G. sa queue arm^e aussi d'un crochet," but 

 it probably only re^jresents one of the hind legs.
