Revision of the Holothurioidea, 
I. Cucumaria frondosa (Gunner) 1767. 
By 
Charles Lincoln Edwards. 
With Plate 13—14. 
In retaining the class name Holothurioidea for this series of 
papers, I have followed current usage. Before accepting so far 
reaching and disturbing a change to Bohadschiidae, as suggested by 
Gızr, 1907, and adopted by Fısuer, 1907, or Bohadschioidea, by 
Pocaz, 1907, I agree with CLARrk, 1907, and Barker, 1907, that we 
should have the question decided by the International Commission 
on Nomenclature. In such a decision I trust with Ber, 1891, that 
common sense, rather than a rigid adherence to the law of priority 
which may be found to apply, will make it plain that we should 
retain Holothuria and Actinia for groups to which they have been 
applied for more than a century. 
In this Revision of the Holothurioidea it is proposed to present 
the results of a thorough study of the anatomical characters of each 
species considered. JÄGER, 1833, SELENKA, 1867, SEMPER, 1868, 
H£rovarn, 1889, Lupwıc, 1889—1892, 1898, 1898a, ÖSTERGREN 1896, 
1898, Mırsukurı, 1897, and Epwarps, 1905, 1908, 1909a, have demon- 
strated that there are differences which make it possible to separate 
the young from the adult. Among the characters which differ in
