taken from the page proof of the article referred to, which was subsequently trans- 

 ferred to volume 40, where the name coccodistoma occurs on page 16. 



In a monograph of the crinoids of Australia, published in 1911, this form was in 

 the text included in multiradiata which was given as occurring at Madagascar and 

 Mauritius; but in a footnote it was stated that the form occurring on the south- 

 eastern coast of Africa, and at Madagascar and Mauritius, differs slightly from the 

 typical East Indian variety, and has been differentiated under the subspecific name 

 of C. m. coccodistoma. 



In my monograph on the crinoids of the Indian Ocean, published in 1912, this form 

 is referred to as Capillaster multiradiata var. coccodistoma and given as from Mada- 

 gascar, littoral and down to 30 meters. In the Siboga report, 1918, it is inserted as 

 a species, coccodisto?na, in the key to the species of Capillaster.

Diagnosis. — A genus of CapiUasterinae in which the arms are more than 10 in 

 number, the IIBr series are 4 (3+4) and the IIIBr series are 3(2 + 3), both being 

 subject to occasional variation and irregularity, the first pinnule of the undivided 

 arms arising from a IIBr or later axiUary is on the first bracliial, there is a syzygy 

 between brachials 2 + 3, except on arms arising from a IBr axillary on which the 

 first syzygy is between brachials 3+4, and the brachials beyond the basal are tri- 

 angidar, about as long as broad, becoming elongate wedge-shaped distally.
