compressed, rather long, 8-jointed; those of the second pair somewhat 
thinner and scarcely longer, also 8-jointed ; all feet hooked, rather long, 
vHth very long , claws ; post-abdomen manifestly articulated, 6-jointed, 
the first joint for a great part covered ; anal segment very large, trans- 
verse and semicircular, with smooth margin ; basal joint of the anal feet 
produced into a point ; branches of the anal feet leaf-shaped, thin, in- 
ternal branch much longer than the external. To this division, belongs 
only the genus 
Saophris, new name for Lobothorax (Bleeker), the authors thinking the 
latter philologically inadmissible. Body of both sexes strongly keeled, 
hinder margin of the anterior segments deeply notched. S. typus 
(Bleeker, Lobothorax ), Batavia, and aurita , sp. n., Ubay, Philippines, fully 
described, pp. 281-28G, pi. xi. figs. 1-4. 
The Cymothoidas , s. str., are subdivided by these authors into two tribes: 
Ceratothoince , antennae dilated or compressed, those of the first pair con- 
tiguous, and Cymothoince , antennae cylindrical, distant at the base. To 
the first tribe, belong the following genera 
Rhexana , g. n. Head small, much immersed ; body flat. R. verrucosa , 
sp. n., Japan, probably the Oniscus ceti of Spengler, 1775 ( [nee Linn.); 
pp. 289-296, pi. xi. figs. 5-10. 
Cleatessa, g. n. Distinguished from the former by the convex body. C. 
retusa , sp. n., Natal and Mozambique; pp. 296-299, pi. xi. figs. 11-17. 
- Glossobius, g. n. Head large, less immersed ; claws of the feet un- 
equal, those of the third pair very large. G. linearis (Dana, as Cerato- 
thoa ) = C. exocceti (Cunningh.) and G. laticauda (M.-Edw., Cymothoa ) = 
C. crassa (Dana), both living on the tongue of several species of Exocce- 
tus in various seas ; pp. 299-315, pi. xii. figs. 1-16. 
Emetha, g. n. Head large ; claws of the feet equal ; summit of the 
forehead covered by the antennae. E. audouini (M.-Edw., as Cymothoa ), 
Mediterranean ; p. 321, pi. xi. figs. 14-18. 
Ceratothoa (Dana). Restricted, distinct from the former by the fore- 
head being prominent between the antennae ; 11 species described and 
figured ; italica , Fiume, gobii, Messina, and collaris, Algeria, are new ; 
pp. 322-371, pis. xiii.-xvi. 
In Nat. Tids. xiv., the same authors discuss the Cymothoince as 
follows : — 
Cymothoa. 17 species described and figured, pp. 222-287, pis. vi.-x., 
including C. curta (on Anableps tetrophthalmus ), exigua, from Panama and 
the Gal&pagos, brasiliensis = ? excisa (Dana), Rio Janeiro, plebeia, Cape 
Verde, gerris, Caxoeira (in the mouth of Gerres brasiliensis), januarii , Rio 
Janeiro (in the mouth of Priacanthus aud Platessa), limbata , Cape York, 
indica } Bangkok, rhina, Philippines, globosa, Atlantic (in the mouth of 
Ephippus faber), truncata and eximia , Indian Seas, and borbonica , Bour- 
bon Island, all spp. nn. ; C. excisa (Perty) = parasita (Reuss), and is 
probably the species mentioned by Marcgrave in Hist. Nat. Brasil, 1648, 
p. 156 ; C. eremita (Brunnich) = cestrum (Spengler) = stromatei 
(Bleeker). Several forms of age and sex are described in some species. 
Telotha , g. n. Antennae as in Cymothoa ; body rather convex, plion 
obconical, the keel of the four posterior pairs of feet less expressed than
