82 BihllograpMcal Notice. 



and of the eight in the first section four names have to be set aside 

 as synonyms. One of these four is thus dealt with in the Addita- 

 menta. In the second section a subgenus of the first genus will 

 have to be renamed if the rules of nomenclature be rigorously 

 enforced. 



None of the genera in the other families are new. The Ligiae 

 include four genera known to the auihor, besides two, or perhaps 

 three, which are cited as unknown to him ; the name of one of the 

 four needs orthographic emendation. The Tylides and Syspastidae 

 contain one genus apiece ; the name of the last genus will have to 

 be sunk in favour of that which it was designed to supersede. 



The number of species new to science that are described is 164 or 

 166, viz. : — oi Armadillo 27, Eabelum 1, Periscypliis 2, Cylloma 1, 

 ArmadilUdium 12, Porcellio 82 or 84, Platyarthrus 1, Onisciis 26 or 

 28, Trichoniscus 2, Ligidium 3, Ligia 3, and 4 of Tylos. 



The following is an enumeration of the total number of the species 

 of all of the genera, combined with synonymic notes : — 



Family Onisci, Section Anna dilloidea . — Armadillo, Dumeril(1816) 

 [«ec Lat. (1804), neque Urisson (17o(j)\=Cubaris, Brandt (1833), 

 enlarged Eaton (1882) {?=Cubaris, Billb. (1820)], 37 good species 

 and 24 sedis incertce.. Mr. Budde-Lund has failed to restore to the 

 first of the species the name assigned to it by Cuvier, and quotes 

 the reference concerning it with hesitation at second baud from 

 Latreille, who blundered unaccountably over Cuvier's unmistakable 

 illustrations of this species. In the discussion of the nomenclature 

 of this genus in Ann. & llag. N'at. Hist. (1882) p. 361, the possi- 

 bility of Cuharis being precluded from adoption as the name for this 

 genus by its having been preoccupied in Crustacea (as indicated 

 above) was not taken into account. The reviewer, writing at a 

 distance from libraries, is obliged to leave undecided the question 

 whether SpJuvrillo or Ortlionas, enlarged in its application, may not 

 have to take precedence over Cidjaris. Enhelum, gen. nov., 1 sp. ; 

 Pseudarmadillo, De Sauss., 1 sp. ; Cercocytonus, B.-L. — Periscyphis, 

 Gerstacker (1873) [misprinted by the author Peryscyphis, passiiii], 

 8 sp. ; Spha'roniscus, Gerstiicker, 1 sp. ; Cylloma. gen. nov., 1 sp. : 

 this genus must be renamed in view of Cyllomus, Hal., and Cyloma, 

 Sharp. Elinna, B.-Ij. = Phacodi'S, Koch (1856), and E. iiurpuras- 

 cens, B.-L. = 7f7i. inscripdus, Koch, the only species. Mr. Budde- 

 Lund, misled by Ebner, quotes Rliacodes as a synonym of Tylos 

 Latreillii; but its identity with ^/i«Hia is unquestionable, and there- 

 fore this last name must rank as a synonym. The name Rhacodes 

 is not invalidated by Rhacodia, Hiibn. (1816) or Schaefi'. (1838). 

 ArmadilUdium, Bdt. & Batzeb., 31 good sp. and 11 sedis inoerta>.. 

 The number 31 may possibly be open to reduction ; some of the 

 structural differences relied upon in the descriptions for the distinc- 

 tion of a few of the species appear to be very like differences depen- 

 dent upon diversity in age of the individual specimens examined. 

 No indication is afforded as to whether Mr. Budde-Lund's conclusions 

 as to the validity of the species to which these remarks arc appli-
