4 DK. T. S. COBBOLD's SYNOPSIS OF THE DISTOMID*. 



identity with FascioJa hepatica clearly established on the author- 

 ity more particularly of I'rofessors Busk and Owen and of Mr. 

 Clapp of Exeter. Full particulars ai'e given in an Appendix to 

 the 1st volume of the Sydenham Society's edition of Kiichen- 

 meister's treatise. Up to the present hour the history of the de- 

 velopment of this species is unknown. The recent investigations 

 of Pagenstecher, Filippi, A¥agener, and others, though they have 

 done much in regard to other species, do not at present enable us 

 to satisfy the inquiries of agriculturists and cattle-breeders, who 

 are so well acquainted with the ravages of this parasite.

ceolatum, antrorsum attenuatum, retrorsiim obtusvim. Cotlum elon- 



gatum cylindricum. Os tenninale, anticura. Acetabulum ore majus, 



superum ad colli basin. Longit. 1-3 unc. ; latit. ^-^ unc.

1856, with coloured figures and anatomical details.

 Hab. I discovered forty individuals in the liver of a young Nubian 

 Giraffe {Camelopardalis Giraffa) which had been exhibited in a travel- 

 ling menagerie in this country for about five months. There also 

 existed in the liver a number of Cysticerci ; as well as three larval 

 Distoraes in cysts connected with the sublingual cellular aponeurosis. 



Genus 2. Campula*, Cobb. 



Corpus compressum, elongatum, armatum. Colluin nullum. Os termi- 



nale. Acetabulum vMwm,yenixa\e, sessile. Trac^ws intestinalis bifur- 



catus, regulse non conseutaneus vel campulatus {kxhttvXos). 



I have established the existence of this generic type, which 



clearly affords additional proof of the accurate views of those ento- 



zoologists who, with Blanchard and others, are willing to retain the 



Fascioles as distinct from the Distomes. This genus forms a 



well-marked intermediate type. 



1. Campula oblonga (Cobbold). — Corpus compressum, ellipticum, 

 retrorsum, obtusum. Collum nullum. Os terminale, ovale. Aceta- 

 bulum subcentrale, superum. Apertura genitalium supra et pone 

 acetabulum. Longit. yV~4 u"c. ; latit. aV^i's imc-

figs. 84 & 85, tab. 33. 

 Hab. I procured about fifty specimens from the liver of a common 

 porpoise {Delphinus Fhocana) in April 1855. They occupied the 

 peripheral extremities of tlie biliary ducts, which were remarkably 

 thickened and knotted. Seventeen individuals were associated together 

 at one spot. From the same Cetacean I removed numerous Nema- 

 ludcs and Cestodes, which are described in the memoir above indicated.
