on the sides of the body; it likewise wants the gray mark which ex- 

 tends from the angle of the month to the pectoral fins. In the figure, 

 the under lip of the Delph. superciliosus is represented as almost white, 

 whereas in the present species it is black : judging from the figures, 

 there is likewise considerable difference in the form. The figure 

 which illustrates this description agrees with the dimensions, which 

 were carefully taken by Mr. Darwin immediately after the animal 

 was captured, and hence is correct." 



Mr. Gould exhibited two species of the genus Ptilotis, which he 

 characterized as Ptil. ornata, and Ptil. flavigula. 



Ptilotis ornata. Ptil. vertice, alarum marginibus externis, nee- 

 non cauda olivaceis ; dorso uropygioque brunneis ; guld, genis- 

 que olivaceo-fuscis ; pectore corporeque subtiis cinerescentibus, 

 singulis plumis notd lata brunned in medio ornatis ; crisso 

 pallide badio plumis fusco striatis, penicilld nitideflavd utrum- 

 que colli latus ornante ; notd longitudinali sub oculos olivaced ;

 albis ; rostro nigrescente ; pedibus brunneis.

Mr. Ogilby read a letter from M. V. der Hoeven, in which the 

 writer expresses his belief that the large Salamander preserved in a 

 living state at Ley den ought to be regarded as a species of Harlan's 

 genus Menopoma ; its specific characters consisting in the absence 

 of the branchial apertures, which are present in the species upon 

 which Harlan founded his genus. M. V. der Hoeven thinks it pro- 

 bable that the branchial apertures were present in the Leyden Sala- 

 mander in the young state, and he proposes to adopt the generic 

 term Cryptobranchus in preference to that of Menopoma, and to give 

 it the specific name of Japonicus. He further states that his obser- 

 vations upon this singular reptile will shortly be published in a 

 Dutch Journal. 



Mr. Owen observed, with reference to the opinion of M. V. der 

 Hoeven respecting the relations of the Gigantic Salamander of 

 Japan to the Menopoma of the Alleghany Mountains, that the persist-
