MONOGRAPH OF THE EXISTING CRINOIDS. 373 



Millport on the Clyde : Dendy found that at Millport on the Clyde the height 

 of the breeding season appeared to be in July. 



Southern Ireland: According to J. V. Thompson the eggs are found on the 

 Irish coast first in July. 



ANTEDON MEDITERRANEA. 



Naples: Gotte gives March as the spawning season. Schmidtlein says that 

 this species breeds in the spring. 



Lo Bianco states that this species reproduces throughout the entire year, and 

 that the months in which individuals with eggs and larvae are met with in greatest 

 abundance are November, December, February, and April. 



Villaf ranca : According to Barrois the breeding season is April. He also 

 states that the first breeding period can be followed by a second and even a third, 

 an assertion partially confirmed by Seeliger's observations on Antedon adriatica. 



Toulon : The breeding season is April, according to Barrois, as at Villaf ranca. 



ANTEDON ADRIATICA. 



Trieste : At Trieste Seeliger found that the chief spawning period commenced 

 in the last days of May and continued until he left at the end of June. At all 

 times it was easy to find a number of individuals with embryos, and toward the 

 end of his visit he found females which had undoubtedly liberated larvae. 



The first sexually mature individual he found on April 25 a female which 

 bore on the pinnules a few embryos, proving on closer examination to be gastrula?. 



It may be that there is more than one breeding period at Trieste, for Seeliger 

 often found embryo-bearing females with nearly ripe eggs in the ovaries. 



COMPSOMETRA LOVENT. 



Whitelegge states that at Port Jackson, New South Wales, the pentacrinoids of 

 this species are often found attached to seaweeds in August and September. 



COCCOMETRA NIOROLINEATA. 



The ovaries of a specimen taken off Habana, Cuba, in January, 1885, contained 

 eggs apparently ready for extrusion. 



COCCOMETRA HAGENII. 



Eggs apparently ready for extrusion were found in the ovaries of a specimen 

 dredged near Key West, Florida, in 122 fathoms, on February 26, 1902. 



PSATIITROMETRA FRAGILIS. 



In a specimen of this species dredged in Yezo Strait, northern Japan, in 

 300 533 fathoms, on September 30, 1906, the ovaries contained eggs apparently 

 ready for extrusion. 



LEPTOMETRA PHALANGIUM. 



Lo Bianco states that at Naples mature eggs are found on the pinnules of 

 this species in January, and that young occur on the cirri of the adults in June 

 and September.
