148 INSECTIVORA. 



The stomach, when inflated, has its apex directed downwards, outwards, and 

 forwards, and the greatest breadth is obliquely across the abdominal cavity from 

 left to right, the apex of the cardiac portion lying close to the vertebral column, 

 directed to the right side, with the pyloric extremity immediately below it ventrally 

 and in the mesial line of the body. The greater curvature of the stomach is thus 

 from behind forwards, which is also the course of the extremely short, lower curvature, 

 which is only one- third the length of the backwardly projecting, upper margin of 

 the cardiac portion. Viewed from the left side, the stomach is seen to be deeper 

 than broad, and to be a truncated cone. Viewing the viscera from behind, the 

 stomach, being inflated, is seen lying below the left kidney, and the latter is almost 

 completely invested on its external half by the large spleen, the outer margin of 

 which nearly describes half a circle. The transverse portion of the pancreas passes 

 upwards to the pyloric angle, at which point a long lobule is prolonged along the 

 greater curvature of the stomach, half-way between the pylorus and the apex. A 

 long process follows the curve of the duodenunl as far as to the apex of the right 

 kidney ; the pancreatic duct opens into the duodenum a short distance beyond the 

 pylorus. The right kidney is at a higher level than the left, and there is a deep 

 hepatic impressio-renalis. The supra-renal bodies are well developed, rather rounded, 

 with one broad and one sharp border, with two flattened external surfaces. The 

 total length of the intestine is about 11 inches, and it has considerable capacity 

 and is of nearly equal width throughout, without any caecum. The heart is elon- 

 gately pyramidal, and is only covered in its middle posteriorly by the left lobe of the 

 lung. The middle lobe of the right lung is only applied to a small area of the 

 right cardiac border, below the right auricle and to the right side of the latter 

 structure in one-half of its extent, the remainder of the auricle having the upper 

 lobe of the right lung on its external aspect. The heart is very large, the upper 

 border of the right auricle being nearly, in a spirit specimen, on a level with the 

 apex of the right lung, the cardiac apex being nearly on the same level with the 

 inferior border of the left lung. The ventricular portion of the heart is half an inch 

 long with a transverse breadth of three lines. The right is considerably larger 

 than the left auricle. The right lung, as observed, consists of three well-marked, 

 deeply-incised lobes, the uppermost lobe being the smallest and the lowest the largest. 

 The left lung is unilobular. The azygos lung is large, more than equalKng the right 

 lobe of the right lung. It consists of three parts, an anterior, rounded lobule which 

 bends round in front of the ascending cava, a posterior, curved lobule between the 

 right and left lungs, and a left lobule between the heart and the left lung. The 

 liver has the right and left lateral fissures deeply incised, but there is no cystic 

 fissure, nor can I detect the presence of a gall bladder. The caudate and Spigelian 

 lobes are well developed. 



By its dentition, if the smaU process on the inside of the first upper incisors were 

 left out of consideration, this aquatic shrew is a Crocidura, whilst if its systematic 

 position were to be determined by its ciliated extremities and almost completely 

 hidden ear, it would be a Crossopus, but the European water-shrew lias 32 red-
