. The cyclopædia of anatomy and physiology. Anatomy; Physiology; Zoology. Male organs of the Water Vole (Arvicola amphibiui). a, glans penis; c, the urinary bladder; d, e, the testicles ; f, g, epididymis, situated at some distance from the testes ; k, I, vesiculaj seminales ; m, n, o, p, </, r, the prostates; s, the rectum, the extremity of which is surrounded by a glandular mass, t, from which a milky fluid is poured into the rectum in the vicinity of the anus, v. In the Alpine marmot it forms a consider- able mass situated above the commencement of the urethra, divided posteriorly into two roundish lobes. In the squirrel the prostate gland 5s as long as the muscular portion of the urethra, to which, however, it is only adherent at the tvo points where its excretory ducts penetrate that canal; in this animal its shape is oval, flattened above, and bilobed posteriorly. In the agouti the prostates (Jig. 282. e, e) assume the tubular form, each gland being composed of a common trunk, divided into branches and ramusculi, ending in vascular enlargements. In the numerous family of rats, the pro- states are represented by several packets of ramified tubes, situated around the com- mencement of the canal of the urethra. Two others are connected with the inferior surface of the vesiculae seminales : these consist of a principal trunk, which has but few ramifica- tions. These latter organs exist likewise in the lagomys, and may perhaps be considered accessory seminal vesicles. The Guinea-pig is furnished with numerous ramified and convoluted tubes, connected to- gether by a loose cellular tissue,which occupy the situation of the prostate gland ofother quadrupeds.
