to A. Milne Edwards, 1878, but first used by Paulson, Investiga

6. Names based on figures without description. Dorynchns first 

 appeared in the combination ' Dorynchus thomsoni Norman,' a 

 species which was figured in the text but not described in 

 Wyville-Thomson's ' Depths of the Sea,' 1873 (fig. 34 on page 

 174). It is referred to thus: "A pretty little stalk-eyed form 

 Dorynchus thomsoni, NORMAN (fig. 34), small and delicate, and 

 very distinct from all previously described species of the genus, is 

 very widely diffused." The italics are my own, and the words 

 emphasized may indicate that the word Dorynchus was accident 

 ally used for Inachus, a genus containing a species dorynchus.^ 

 Dorynchus thomsoni was described and figured in a new genus by 

 A. Milne Edwards, Crust. Reg. Mex., 349, pi. XXXI A, fig. 4, 

 1880, as Lispognathus furcillatus. Later J Prof. Milne Edwards, 

 after recognizing the identity of his species and D. thomsoni, 

 refers to it as ' Lispognathus (Dorynchus) Thomsoni.'' In 1886 Mr. 

 Norman, in his ' Museum Normanianum. Crustacea,' enters the 

 species as ' Lispognathus thomsoni,'' although more recently (De 

 cember 21, 1895) he has assured me that he sees no reason why 

 Dorynchus should be displaced. 



A different case is that of Planes, a manuscript name of Dr. 

 Leach, published by Bowdich, 1825, the claims of which are set 

 forth by Dr. Faxon in his report on ' The Stalk- Eyed Crustacea ' 

 of the 'Albatross,' p. 29, 1895. This name is based on plate fig 

 ures. In the text, p. 15, Bowdich says : "A small crab, fig. 3, 

 a and b, which I conceive to be a new species of planes, was found 

 in great numbers amongst the anatiferx. [Foot-note :] It was 

 of a delicate, but bright, rose colour : from the symmetrical form 

 of its test (notched so regularly as to increase the projection and 

 distinctness of its chaperon) it may be called p. clypeatus"

t Inachus doryncJius Leach, 1814, should be known as Inachus phalangium 

 Fabricius, the Cancer phalangium of Fabricius, 1775, of which 1 have ex

 synonym of MctCfOpodia roxlrafa (Linmeus), 1701.
