This paper deals priacipally with the mouth-organs of the Isopoda. Of the biting Isopoda the 

 mouth is said to present three principal types, and the first type is said to comprise Onigci, 

 AseUi, Idotheas and Si^hxromata, and to be essentially the same as the type met with in the 

 majority of the Amphipoda.

Spence Bate demurs to Grube's view that " Allorchestes imhricatus (Sp. B.), is but the young of 

 A. helleri." He " suggests to continental carcinologists to determine whether or not there 

 be two freshwater species [of Gammarus\, viz., G. pulex and G. fluviatilis, as, from the 

 great confusion of the two names by various authors, he is inclined to think that they, and 

 also the figures, are but the result of imperfect drawings and descriptions of one and the 

 same species." Oammariis torelli, sp. n., Goes, he says, "evidently belongs to the genus 

 Megamcera of the Brit. Sessile-eyed Crustacea.'' In the " Naturalist in Vancouver Island 

 and British Columbia, by J. Keast Lord. London, 1866," vol. ii., ch. xiii., pp. 262-284, 

 with a plate, a description is given by Spence Bate of the "Vancouver Island Crabs." In 

 this chapter, he mentions from Esquimalt Harbour, Allorchestes verticillatus, Dana ; 

 Allorchestes hrevicornis, Dana; Mmra fusca, Sp. Bate; Amphithoe pcregrina, Dana; 

 Am2Mth{)e orientalis, Dana ; Amphithoe lilicornis, Dana.

It mentions 72 species of Crustacea, the principal object being to show the sjiecialities of the 

 Italian waters, as discovered by Cocco, De Natale, O. G. Costa, Hope, and A. Costa 

 himself. The numbers 32-59 refer to the Amphipoda. 35 is Orchestia crassicornis, n. s., 

 near to Orchestia littorea, "but differing in the proportions and robustness of the lower 

 antennw, especially of the male. They are shorter and more robust than in the three 

 allied species, littorea, mediterranea, and constricta." On 37, Orchestia deshayesii, 

 Audouin, it is remarked that the hand of the second gnathopod varies greatly. 40, 

 Lysianassa Jilicornis, A. Costa, "by the length and tenuity of the lower antenna; 

 approaches L. longicornis, Lucas, from which it is distinguished chiefly by the proportions 

 of the upper antennte, those of the abdominal false feet and other characters. Neverthe- 

 less, the two species in question, on account of the extreme length of the lower antennae, 

 may very well constitute a distinct group or subgenus, for which we have proposed the
