" Acanthonotus (Vertumnus) Testudo, White, Proa. Zool. Soc. Lond. 1850, t. f." 



To the genus Gammarus, Wliitc now adds, Gammarus subterraneus. Leach, which he suspects 

 may be " Gammarus pulex, var. jun.? " ; Gammarus caritiatus, the Keeled Coast-Screw, 

 " Johnston, Zool. Journ. iv. p. 52 ; " Gammarus mwulatus, the Spotted Coast-Screw, 

 Johnston, Zool. Journ. iii. p. 176; while Gammarus campylops. Leach, is now given as 

 Gammarus camptolops, the Bent-eyed Coast-Screw. In the Podoceridje, " Jassa, Leach, Ed. 

 Enc. vii. p. 433 (1814 or 1815)," receives the two species in the earlier list assigned to 

 Cerapus. To the well-known Cvrophium, is applied the English title of " Long-horned 

 Mud-Liver." The Family Cheluridee is occupied by Chelura terebrans, " Sea Wood- 

 borer," Philippi's names for the genus and species being rightly preferred to the older MSS. 

 nameSj Ke/nertes nesxoides. Leach. 



To the family Typhidse is added Typhis nolens, for " Gammarus nolens, Johnston, Zool. Journ. 

 iii. p. 179." 



Among the CaprelHdaj, Leach's CapreUa acanthifera, Spined Skeleton-Screw, displaces the name 

 Caprella acuminifera. Leach, and the additional entry is made of " CapreUa lobata, Miiller, 

 Kroyer, Voy. Scand. et Lapon. Crust, pi. 25, f. 3, a.; Tliomp. {W.) Ann. Nat. Hist. xx. 

 p. 244." Lastly Proto pedatum becomes Proto pedata, Miiller's Spectre Shrimp. 



\\\ the family Cyamidse, the species are given as " 1. Cyamus ceti. Common Whale-louse," 

 including in the synonymy Cyamtis erraticus, Roussel de Vauzeme, with Oniscus ceti, Linn., 

 etc., etc.; "2. Cyamus ovalis. Oval whale-louse," and " 3. C;/a7»M.s //I'aa'/M, Slender Whale- 

 louse." A concluding observation says, "Here by many anthor.s are placed Nymphon, 

 Pycnogonum, and their allies." 



Most of the species are designated by English names similar in character to those which have 

 been quoted.

After describing Potamohius serratus and Gonodacfylus cultrifer, n. s., which are figured on 

 Pis. XV. and XVI., White says, " On the same plate with G. cultrifer is figured an 

 Amphipod, which 7nay be the species figured by Colonel Montagu in the ninth Volume of 

 the ' Linnean Transactions,' t. 5. f. 5, under the name of Oniscus Testudo. I have named 

 this on the \Aa,te Aca7itho7iotus Testudo: it belongs to Prof. Owen's genus Acantltonotus : 

 in the British Museum it bears Dr. Leach's manuscript name, Vertumnus Crancliii. The head 

 is produced and pointed between the antennse, and instead of the small number of segments 

 assigned by Colonel Montagu to his Oniscus, there is the normal number of the various 

 genera of Amphipoda." 



It was afterwards recognised that this species has nothing to do with Montagu's Oniscus testudo, 

 and that it does not belong to Owen's genus Acanthonotus, but to the neighbouring genus, 

 Epimeria, of Costa, being in fact Epimeria cornigera, Fabr.
