Liriope tetrapJuylla — material examined. 



The specimens range from 8 to 16 mm. in diameter, and are all in 

 what I have called the "rosacea" stage (1909a), as were all but the 

 smallest (less than 5 mm. in diameter) described by Maas (1909) 

 from Japan. It has been described so fully by him (1905), by 

 Hartlaub (1909), and by the writer (1909a) that a brief statement of 

 the growth condition of the present series will suffice here. 



Maas found that the first trace of gonads appears in specimens 

 3 to 4 mm. in diameter, and that at first they are oval, just as I 

 described them from the eastern Pacific series. This outline, how- 

 ever, is transitory, the triangular form being attained in specimens 

 5 to 6 mm. in diameter. This, of course, explains the fact that it 

 was only the very smallest specimens of tetraphylla from the eastern 

 Pacific, 7 mm. or less, that had oval or squarish gonads. Therefore 

 it is not surprising that the triangular outline is universal in the 

 Philippine series, all of which are 8 mm. or larger. 



The gonads are not in contact in any of the specimens, nor were 

 they in the Japanese examples of about the same size (12 to 14 mm.; 

 Maas, 1909, p. 31). In the eastern Pacific collection it was only in 

 specimens 18 mm. or larger that they were large enough to touch 

 each other, while in none smaller than about 20 mm. did they show 

 the pentagonal form typical of the " compacta " stage (Bigelow, 

 1909a) . But in one specimen from the northwest Pacific only 12 mm. 

 in diameter one gonad was pentagonal (Bigelow 1913, p. 55). 



Most of the specimens have three blind canals in each quadrant, 

 but one 16 mm. in diameter has four in one, three in each of the 

 others. The other specimens of this size, of which there are four, 

 are badly damaged. Maas (1905, 1909) found more than three canals 

 only in specimens 18 mm. in diameter and upward.
