46 SOLENODON PARADOXUS. 
organ is large and composed of three main lobes whose appearance is essentially 
like that in Centetes. The left lateral lobe is large and rather oval, slightly less 
in breadth posteriorly than anteriorly. It is without secondary divisions. The 
right lateral lobe is of smaller diameter and subcylindrical, consisting of two 
portions: the main lobe proper and the caudate division. The latter is large 
and of practically equal length with the main lobe into whose dorsal surface it is 
A 
received by a deep groove. The sides of this groove enfold the caudate lobe so | 
that its exterior surface is continuous with that of the rounded main lobe. 
The distal ends of the two appressed lobes are hollowed to receive the anterior 
end of the right kidney, which they thus together surround. In Gymnura the 
caudate lobe is represented as long and narrow, and alone enfolding the end of 
the kidney. In Erinaceus the condition is much the same. The Spigelian lobe 
is very short and single, thus resembling that of Centetes, rather than that of 
the Erinaceidae in which it is generally larger in proportion and bifid. The 
central lobe of the liver is practically entire except for a slight fissure at its left 
end, visible in ventral view, but covered dorsally by the gall bladder. The dorsal 
surface is deeply grooved for the reception of the pyriform gall bladder, which is 
partially overhung by a projection of the substance of the liver. The suspensory 
ligament is attached along the median portion of this central lobe for some 
18 mm. Posteriorly a small thread-like division of this ligament is given off to 
the tip of the secondary lobe separated off by the shght fissure previously men- 
tioned at the left side of the main central lobe. The gall bladder is large and 
pyriform and its duct, about 30 mm. in length, opens into the small intestine in 
common with that of the pancreas at about a centimeter from the pylorus. 
The pancreas (Plate 9, fig. 7) is a large structure with very definite outline, 
and consists of two main lobes. The one is elongate, about 55 mm. in length by 
15 in width, and of a slightly reddish color. The other is subtriangular, and 
much more solid in consistency, becoming decidedly thickened at the free 
rounded apex. The duct is confluent with that from the gall bladder at about 
6 mm. from the opening into the small intestine. There are no secondary 
pancreatic ducts. The great size and solidity of the pancreas are noteworthy 
in Solenodon paradoxus. The slight and racemose structure figured for this 
organ in S. cubanus (Peters, ’64, Plate 2, fig. 10) is quite different and may be 
the result of partial decomposition. . In its bilobed character and the stoutness 
of the large triangular portion, the pancreas of S. paradoxus seems to bear much 
resemblance to that of Chrysochloris.
