what J. P. Hill and I found in the platypus. Corner figures more cicatricial 

 elements in the sow, but not nearly so many as occur in the platypus. 



In PI. Iir, fig. 2, the so-called lutein granules have been added, from a 

 study of osmic preparations, but in fig. 3, this has not been done. 



In PI. IV, fig. 4, there are five or six lutein cells shown surrounding a 

 stellate chromophile cell. Each lutein cell has an enormous Golgi apparatus 

 [G-] nearly always larger than the nucleus itself. The Golgi apparatus never 

 shows a network, but it is made up of single granular or rod-like dictyosomes 

 which form a spherical structure, throughout all parts of which granules exist. 

 There is no evidence of a cortical arrangement of dictyosomes. In some cases 

 nearly half the cell is occupied by this large Golgi apparatus. In PI. IV, 

 fig, 4, the lutein granules have been added from a study of Schridde and 

 Sjbvall preparations, but in fig. 5, the cells are drawn exactly as they appear 

 in Da Fano preparations : it should be mentioned that in many of the better 

 preserved Da Fano cells, the lutein granules appear as chains of empty 

 vacuoles. 



In PI. IV, fig. 4, the chai-acteristic arrangement of the lutein granules is 

 shown. They are arranged exactly like the mitochondria of many tissue and 

 genital cells, in irregular chains and groups of discrete granules, occupying the 

 space left between Golgi apparatus, nucleus, and the cell wall. 



The nucleus of the lutein cells contains one or two elongate oxyphile 

 nucleoli, and is amphophile with basophil preponderance in Mann's methyl 

 blue eosin. 



The ground cytoplasm of the luteal cells becomes very reticular in fat 

 solvent fixatives, and is in this way quite different from that of the stellate 

 chromophile cells. 



- (b) The Stellate Chromophile Cells?- 



The remarkable cells drawn in PI. Ill, figs. 2, and 3, 1*1. IV, figs. 4 and 5 

 {AS), I have called stellaie chromophile cells : these are probably a normal 

 constituent of the human corpus luteum. Two similar cells are given in 

 PL I, tig. 3 b, of Uorner's paper, and, as I have already remarked, these cells 

 appear to have been noted first by this observer. Corner describes his cells 

 as '• ranging in shape from spindles to branching and spherical forms," and 

 this agrees fully with the illustrations given in the present paper. Corner 

 speaks of such cells as a normal constituent of the sow's corpus luteum, so 



' Preparations of liuman ovary recently made (January, 1924) show that the stellate 

 cells are theca interna elements ; in the wall of the ripe Graafian follicle the theca interna 

 cells stain like the stellate cells of the corpus.
