 B. li<vin((tUicns, B. sicperciliiD^s, and B. cracifer. Of the Cysti- 

 giiathidie, on tlie other hand, there were representatives of no 

 less than twelve genera and nineteen species : — Ceratohj/la 

 hahalun, Pseiidis paradoxa, Cahjptocephalus gnyi, Telmatohius 

 jMcii, Ceratophrys ornata, 0. boiei, Chiroleptes australis, 0. platy- 

 cephalus, Heleioporus albopunctutus, H. pictiis, Hylodes lineatus, 

 II. raiiifonnis, II. Jleischmanni, Cryptotis breuis, Limnodynastes 

 tasmuniensis [2], L. dorsalis, L. ornatus, Leptodactylus penta- 

 dac.tylan, and Hylorhina silvatica. The closely related Dendro- 

 phrym'scinai are represented in the British Museum Collection 

 by a skeleton of Batrachophrynus bracliydactylus, which was also 

 procooloiis. 



Among the forms included in the Eugystomatidae and Dysco- 

 phidse, three specimens (representing two genera) were found 

 to retain the strictly procoelous condition. These were Ilhombo- 

 phryne testudo, AteJojjus oxyrhynchus and A. ignescens, each 

 represented by but a single specimen. The majority of the 

 specimens exhibit the diplasioccelous condition, which was seen 

 in eight genera, viz. : — Breviceps (B. verrucosus, B. mossambicus), 

 Calophrynus (C. pleurostigma, C. madagascariensis\ Scaphiophryne 

 (S. marmorata), Cacopus (C. systoma), Ccdhdops (0. dorice), 

 Callida (C. pidchra), Hypop^'uhus {II. variolosus)^ and Oenophryiie 

 (G. thomsoni). 



Among the Ranidoe the diplasioccelous condition also prevails, 

 only five specimens (referred to four species of lihacoplwrus) 

 being found to retain the more primitive procoelous condition. 

 The spHoimens of this family which have been examined include 

 the following : — Ilylambates {II. angolensis), Trichobatrachus 

 (T. robustits), Gampsosteonyx (G. batesi), Rana (li. clamata, 

 7?. tiyrina [35], R. agUis, R. adspersa, R. latastii, R. afghana [2], 

 R. inontezanuii [2], R. catesbiana, R. galamensis, R. guttidala, 

 R. ficscigida, li. macrodan, R. gracilis, R. cyanojMyctis, 

 R. escidenta [12], R. grunniens, R. erythrcpa, R. malabarica, 

 R. beccarii, R. jdeiiraden, R. adenopleura, li. jerboa, R. arvcdis, 

 R. camerani, R. grceca, R. iberica, R. pcdustris, R. madagascari- 

 ensis, R. boyli, R. oriiatissinia, R. liebigii, R. hexadactylas, and 

 R. temporaria [about 160]), RhacopTiorxts (R. maculatus, R. cru 

 ciger, R. fjoudatii, R. macrotis, R. robustits, R. schlegeUi, R. rein- 

 toardtii [2], A*, maximus, and R. madagascariensis), Chiromaniis 

 (C. petersi), Corniifer (C. corrugatas), Oxyglossus {0. Icevis), 

 Tympanourus {T. neivtoui), Oxyrhachis kevis, Arthroleptis 

 {A. rariabilis), and Ceratobairachus gueatheri [2]. 



in by far tiie greater number of cases, disarticulated vertebral 

 columns were not available, but this circumstance presented no 

 •serious difficulty since the condition of the vertebral centra can,
