 r»l, (ij;. IS) tli(.> tliiiljiiiii'ii(!C'i>liiili)n is more entonsively exposed tliaii in 

 other Saiieiitia.* 



Tlio f'oiin of tlie livoi- docs not (lillcr from tlic usnal typo in any 

 of the various spoeies examined, exeept in th« Finnisteniia. Whihi 

 most Salieiitiii have this or^an divided into three lobes, tlierc are but 

 two ill tiio J>i'evicii)itidie, l']ii;;ystomida', and some of the Pliryniscid;e, 

 III tlie aliinentaiy canal there appears to be little variety in important 

 points. Tlie stomach has <feneraily a more loii;;;itiidiiial position than 

 amoiijL;' Uiifoiiiforinia, excei)t ainoii;^ Scapliiopidie and in Ceratophrys, 

 where it is e.pially transverse, Xo intestinal valves were observed in 

 I'elobates, llyla, riiyllomediisa. Ceialophrys, but a stronj;' pyloric mns- 

 cnlar coiistri(!tion in IMeiirodeina, and oik^ at the extremity of the small 

 intestine in Cifsti(in(itliit>; parlii/inis. (IMates n,")-.")/;.) 



The testes are sin;;le in e\'iiin|)les of all tli > types evamincd, and not 

 stri(!tly symmetrical ; they are variously situated with rel'ereiic*' to the 

 kidneys. Thus in h'tiiioiilni aiircii, and Tntclii/crplKilii.s licliciiiitii.s they 

 are eloii;;ate and at tin' middle of the leiijuth of the kidneys, while in 

 Ili/jiishixts hofdis and tSci/lojtis romlosiis they are oval, and one or both at 

 the aiitcri(n' extremity of the latter. In rin/llitmcdiisa srlrnnlcrma they 

 are more than half the length of the broad kidneys, the rij^lit ori;;iiiatinj; 

 at the anterior extremity of the latter, tlu^ left but little behind it. JJotU 

 have their jnysterior a[)ices in close contacit at lie posteri(U' fourth of 

 the leiifilh of the kidneys, which are in close connection for their poste- 

 ri(n' third. In lMsco_!;lossns the testes i\n> oviform, well separated, and 

 anterior, and diiriiiij; the breodiii.i,' season attain a remarkaltly lar{>e 

 size. Dnriiij-' the same in Vi/stiffntitlitts lutchi/pitsthoy are not materially 

 eiilarjjed, are elon;;ate, and only in contact with the kidneys for a 

 small postcrioi' part of their lenjith. 



The ovaries and oviducts do not essentially vary among the Salientia 

 When the latter are fnlly occn[)ied l)y eggs in an advanced stag(^ they 

 arc folded, but ditVerentlv in the same species. The ovidnctts are I'e- 

 inarkably slender in Ili/hi iiKsuta (Litoria (liinther), and in Scj/ 1 njti.s tha 

 foiitanclle is on ca(;!i side behind the partial diaphragm, at the superior 

 anterior outer angles of the liver. In several young female si>ccimens 

 of linnoulva aurcn of the size of Hana Nilrd^'iat, in which the frontop- 

 arietal Ibntanelle is not closed, the oviducts do not extend farther an- 

 terior than the ovaries; in adults, with the cranium complete, they 

 have the usual extent. In ('iistifinntlius ocellatus the ''uterine" sacs at 

 the exit of th(M)viducts are of greiit size, and at oertain seasons dis 

 tended with an albuniiiious gelatine, when they present several coiivo 

 liUions. In spirits they occasion the ])resence of a large convoluted 

 mass of coagnlnm.
