OPHIURANS OF UNITED STATES NATIONAL MUSEUM. HI 



The diameter of the disk is generally about 10 mm.; in the larger specimen it 

 is 13 mm., and in the smaller 5.5 mm. 



The description which has been given by L3Tnan of 0. valida was established 

 on some young specimens; it was completed by Verrill, who made this species the 

 tjTJe of the genus Ophiomitra, s. str., and I can but refer to that author's work. 



0. valida is not much known, except in the Caribbean Sea and on the coasts of 

 Florida, but it has a vcrj' wide bathymetrical distribution, for it is said to extend 

 between 10 and 1,105 fathoms.

 Koehler (09), p. 195. 



Albatross, 1886. Bahamas. No depth mentioned. One specimen. 

 The specimen is in very bad condition; the upper face of the disk has been torn 

 out and the arms are broken about the base, but still it is quite characteristic.

Havana, three specimens; no depth indicated. 



Tlie diameter of the disk ranges between 7 and 10 mm. I have mentioned 

 these specimens in the description which I have recently given of this new species, 

 to which please refer.

About this species there has arisen a very unfortunate confusion and I am glad to 

 avail myself of the present oi^portunity to clear it up. This confusion is accounted 

 for by some delays, due to no fault of mine, in the printing or pubUshing of pre- 

 liminary notes or of final papers in which I gave the description of this Ophiuran. 

 I had introduced the genus Ophioleda and described 0. minima in volume 19 of tlie 

 M^moircs de la soci^t6 zoologique de France; my manuscript, transmitted in 1907, 

 was not pubhshed until 1908 in a volume dated 1906; meanwhile, the report of the 

 Expeditions Scientifiques du TravaiUeur et du Talisman containing my final paper on 

 the Ophiurans gathered by these two vessels, had been published (1907). On the 

 other hand, in the same year, 1907, 1 had described the same species under the name 

 of Ophioplinthaca occlusa, in the preliminary note No. 99 in the Bulletin du Mus^e 

 Oc^anographiquo de Monaco, without having been able to record on the proofs 

 the synonymy of that species; the same text was printed, about the same time, in
