Abstract
Porphyrin が広く鳥類の卵の外皮に分布することは明らかにされているが，卵管における形成と卵への沈着の機序は明らかでない.別報で著者らは，卵の外皮の本色素の分布を示したが，今回は卵管の本色素の分布を検索した.材料としてウズラ，ニワトリ(ロード・アイランド・レッド，白色レグホーン)を用いて，次の結果を得た.
肉眼的には，各卵管の子宮部粘膜に特異的な禍色の帯色をみとめ，それと一致して赤色~桃色螢光がみとめられた.これらの性質から， porphyrin 色素が分布していることは明らかである.その色調と螢光はウズラで著名であるが，ニワトリでは淡く弱い.
子宮部組織の凍結切片の観察では， 3種の烏の各組織で粘膜上皮に限って赤色~桃色螢光がみとめられるが，ウズラで最も著名である.該上皮には，卵殻形成時のウズラで褐色色素穎粒が容易にみとめられるが，他のものでは検出し難い.何れの卵管でも，子宮腺には色素穎粒はみとめられない.
子宮部のパラフイン切片での詳細な観察では，ウズラとロード・アイランド・レッドで粘膜上皮に色素穎粒がみとめられるが，白色レグホーンではみとめられない.子宮腺lこは，何れでも色素穎粒がみとめられない.

Abstract
Macroscopical and microscopical observations were made on the oviducts of the Rhode Island Red, White Leghorn and quail, with special reference to porphyrin pigments. The results obtained are summarized as follows.
Macroscopically, the mucous membrane of the uterus in each bird was colored in various brown and fluoresced red to pink. The brightness of fluorescences was related with the depth of the colorations, and they were distinct in the quail uteri, showing dark brown coloration and red fluorescence, and were moderate, showing light brown and pinkish fluorescence, in the Rhode Island Red and White Leghorn uteri.
In frozen sections, distinct fluorescence and collected brown pigment granules were observed in the mucous membrane of the uterus in some cases of the quails. In the uteri of the others, weak fluorescences were observed, but the pigment granule was unobservable.
Through the careful searching in the paraffin sections, the pigment granules were revealed in the mucous epithelium of the quail and Rhode Island Red uteri. Neither the fluorescence nor the pigment granule was found in the uterine gland in
each material.
From these findings, it was concluded that fluorescent porphyrin pigments were distributed in the mucous epithelium of the uterus in the quail, as well as the Rhode Island Red and the White Leghorn, although "pigment granule" was invisible in the sections of the White Leghorn uteri.
