500 THE VOYAGE OF H.M.S. CHALLENGER. 



with whicli it has a mandibular palp, the flagellum of the lower antennse consisting of more 

 than two articulations, branchia3 on the second, third and fourth peraeon-segments, and a 

 pleon with two pairs of appendages in both sexes. 

 The three species of Nicea may be assigned to the genus Hyale, as in each the telson is deeply 

 divided ; for the species of Calliope, the altered generic name Calliopius has since been 

 adopted ; Gammarus harhimaniis has been recognised as identical with Coroiihium lemlen- 

 feldi, Chilton, 1883, and by Thomson and Chilton, 1886, called Corojihium harhimanum, 

 with Haplocheira typica, Haswell, in the synonymy ; but the right name will, I think, be 

 Haplocheira harhimanus ; Platijscelus intermedms, if really distinct from sei'ratus, which 

 Claus identifies with ovoides, will become Dithyrus intermedius. For the species described 

 as Lysianassa liroyeri, Spence Bate {EpMppipjlwra kriiyeri, White), see Note on Miers, 1884, 

 and Note on Thomson and Chilton, 1886 ; Paramosra tenuicornis, Miers, Mr. Thomson says 

 "must be replaced in the genus proposed by its original describer, Dana, viz., Melifa." 

 The sexes and young of Themisto antarcfica, Dana, are described, but specimens which 

 Mr. Thomson has had the kindness to send me, with this name attached, belong, I believe, 

 to the genus Parathemido. The minute illustrations to this paper by no means fairly 

 represent Mr. Thomson's own drawings, for " instead of lithographing the plates, the 

 draughtsman traced them on to a large sheet, from whence they were photo-lithographed."

A short description is given of Mr. Thomson's earlier paper in the New Zeal. Inst. Trans., 

 and four more species are added to the local fauna: — "L AmpJiitJionotus Isevis, sp. nov. 

 (PI. XVI. figs. 1-4.)." "Though agreeing closely in generic characters, this species is very 

 di.stinct in appearance from A. Edwardsii, as figured in the British Museum catalogue, and 

 also apparently from A. spiniventris, Costa," in regard to which it must be observed that, 

 of the two species compared, the former belongs to the genus RTiachotropis, the latter to 

 Dexamine ; "2. Aora typica, Kroyer," in which "the superior antennae were about as 

 long as the animal ; the propodos of the first gnathopoda, as well as the last four joints of 

 the second gnathopoda, were very hairy ; telson quite smooth "; " 3. Microdeutopug 

 maculatus, sp. nov. (PI. XVI. figs. 5-8)," accepted by Thomson and Chilton, 1886, as the 

 female of Aora typica, Kroyer; "4. Cyrlnphiiim cristatum, sp. nov. (PI. XVI. figs. 9-15)." 

 " This species differs from the generic characters of Cyrtop>hium in possessing an appendage 

 on the superior antennae ; but as it agrees in every other respect, I do not feel justified in 

 placing it in a new genus. It comes nearest to C. hrasiUense, obtained by Dana in the 

 harbour of Kio Janeiro." Dana's species here referred to is Platopldum brasiliense.

This paper, the first of an important series, is on new Peruvian species of the genus Hyale, 

 Rathke, which genus, in the wider sense accepted by Boeck and Stebbing, he thinks may 

 be conveniently divided into two subgenera, the one AUorchestes, Dana, with telson simple
