362 THE VOYAGE OF H.M.S. CHALLENGEE. 



Trypliosa nanoides by Boeck, 1870; 5. Anoriyx pumilus, n. s., PI. iv. fig. 35-41; 

 6. Anonyx hraclujcerais, n. s., PI. iv. fig. 42-49, called Menigraies hraclujcercus by 

 Boeck in 1870; 7. "Anonyx Bruzeln," Boeck, which is recognised as standing near 

 Anonyx gulosus, and was subsequently regarded by Boeck himself as a variety only of that 

 species, see the table of errata and addenda to De Skand. og Arkt. Amph.; 8. Anonyx 

 nanus, Kroyer, by Boeck in 1870 called TryjjJiosa nanus; 9. Anonyx pinguis, Boeck, 

 later called Orelwmene pinguis by Boeck; 10. Anonyx serrahis, Boeck, PI. iv. fig. 50, 

 afterwards called Orchomene serratus by Boeck ; it is here identified with Anonyx 

 Edtpardsii (Spence Bate), but wrongly according to Sars ; 11. "Anonyx Edwardsii," 

 Kroyer, afterwards called Onesimiis edwardsii by Boeck; 12. Anonyx litoralis, Kroyer, 

 called Onesimus litoralis by Boeck; 13. "Anonyx HolholUi," Kroyer, called Hipp)omedon 

 liolbulli by Boeck ; Anonyx denticulafns, Spence Bate, is here said to be the male of this 

 species; 14. Anonyx ohtusifrons, Boeck, which was afterwards called Blenigrates obtusi/rons 

 by Boeck ; 15. Anonyx tuniidus, Kroyer, PI. iv. fig. 51, which Boeck calls Aristias tumidus. 

 Boeck, it will be observed, requires seven genera for these fifteen, or perhaps thirteen, species. 

 Anonyx hruzelii falls to Anonyx gulosus (cicada), and Anonyx hracliycercus is considered 

 by Boeck, in 1876, to be a synonym of Anonyx (Menigrates) ohtusifrons. In Lilljeborg's 

 synoptic table Anonyx hrachycercus is separated from Anonyx ohtusifrons by the maxilli- 

 peds. In bracJiycercus these have the outer plates large, "ultra medium articuli 3:tii 

 palpi extensse, ad marginem interiorem tantummodo apicem propius nodulosae, nodulis 

 discretis 4, et ad marginem exteriorera setam unam et pilos minimos gerentes," while in 

 ohtusifrong he finds from Boeck's description that these plates " have some few scattered 

 coarse teeth on the inner margin." These delicate characters seem little suited for important 

 subdivisions. I am inclined to think that the teeth on the inner margins of the outer 

 maxilliped-plates are very liable to accident, so that their absence cannot always be depended 

 on as characteristic. 



The fourth genus, Callisoma, Costa, has the species Callisoma Tiriiyeri, Bruzelius. 



The fifth genus, Acidostoma, which is new, is thus defined : — 



" Forma corporis et antennarum cum genere Anonycis congruif, oi'is partes ajjjjendiculares tainen 

 plane diversx. Lahii rami latei-ales angusti. Mandihulx processu accessorio, maxillx l:mi 

 parts pcdpo, et palpus maxillipedum ungue carentes, et hx paries oris eonjunctim acumen 

 productum prsehent. Pedes trunci l:mi paris rohusti, manu prelieusili. Pedes 2:di imris 

 graciles, ungue carentes." To this genus, as the type species, is referred Anonyx ohesus, 

 Sp. Bate, which is described and figured, PI. v.

 of Natural History. Series 3. Vol. XV. 18G5. pp. 27G, 277. PI. X. 



The new genus, Batea, is thus defined : — " Antenna? simple. Coxa of the first pair of gnathopoda 

 rudimentary, those of the second pair of gnathopoda and the first two pairs of pereiopoda 

 largely developed. Coxa of the second pair of pereiopoda deeply excavated upon the upper 

 part of the posterior margin. Eirst pair of gnathopoda rudimentary, consisting of coxa and 

 basis only ; second pair of gnathopoda subchelate. Mandibles having an articulated 

 appendage. MaxiUipeds having a squamiform plate on both the basis and ischium joints. 

 Fourth and fifth pairs of pleopoda with styliform rami, sixth pair with subfoliaceous rami. 

 Telson single, deeply cleft."

Fritz Mtiller dates from Desterro, Brazil. He gives figures of the male, and notes in his
