The distribution of portal veins within the liver in 30 Korean native cattle were observed. Vinylite solution was injected into portal veins of eighteen specimens for cast preparation. The angiography was prepared in twelve specimens by injecting 30 % barium sulfate solution into portal veins, and then radiographed on an X-ray apparatus (Shimadzu 800 MA 120 Kvp). The Vena portae was divided immediately upon entering the liver into a very short Truncus dexter venae portae (14.75 +- 4.86 : 6.9-23.1mm) and a long Truncus sinister venae portae (94.16 +- 9.62 : 110-150 mm). The Truncus sinister venae portae runs of first in the long axis of the liver from the porta hepatis toward the left lobe. At the boundary between the quardate and left lobes it bends sharply 50 to 80 degrees toward the Incisura ligamentum teretis, and after a course of 36.5 to 54.3 mm between the quadrate and left lobes, ends abruptly. The Truncus sinister venae portae is divided for description into the Pars transversa, from the Porta hepatis to the flexure, and the Pars umbilicalis, from the flexure to the end. The branches of Venae portae were Ramus ventralis lobi sinistri, Ramus intermedius lobi sinistri, Ramus dorsalis lobi sinistri, Ramus lobi quadratti, Ramus ventralis lobi dextri, Ramus intermedius lobi dextri, Ramus dorsalis lobi dextri, Rami processus caudatorum and Rami processus papillarum. The Ramus intermedius lobi sinistri arose from the left surface of the Pars umbilicalis, and was origined on the common trunk with Ramus dorsalis lobi sinistric (3 cases, 10 %) or Ramus ventralis lobi sinistri (3 cases, 10 %). The Rami lobi quadratii consisted of the vein (15 cases, 50 %) or two veins (15 cases, 50%), and was observed on the arched-shaped at 2 cases (6.6 %) of the liver. The Rami processus caudatorum consisted of one vein (28 cases, 93.3 %) or two veins (2 cases, 6.6 %). The former were formed common trunk with R. dorsalis lobi dextri (7 cases, 23.3 %) or R. ventralis lobi dextri (2 cases, 6.6 %)

A migratory bird, the white stork Ciconia boyciana was captured from a pond in the Chejudo, Korea R. on the 18th of Dec. 82. The morphological characteristics were described as seen in the binocular stereoscopic microscope and further fine structures were observed by means of the scanning electron microscope (model; ISI-DS-130). The bird was examined for ectoparasites at the Cheju Provincial Veterinary Research Lab. Two kinds of specimens were collected from the head and body feathers. The specimens were sent to the Inst. of Veterinary Research in Anyang, Korea R. for classification and identification

This study was to investigate the development pattern of epididymis in accordance with the growth of meat-type cockerels. Histological features of various ductules in epididymis of the cockerel on the age of weeks were within 10 weeks after hatching rete testis and connecting ductules were well developed but efferent ductules were observed in immature form. During 10th to 20th week, the lining epithelium of various ductules in epididymis was in the developing stage near to the mature form
