70 A HISTORY OF RECENT CRUSTACEA 
having deep red patches and interlacing lines. The 
following pairs of feet are yellowish with faint red lines, 
the last pair being marbled with red, its joints very broad, 
and the last of them thin and membranous. By some 
writers this species is called Goniosoma cruciferum (Fabri- 
cius). They would displace de Haan’s Charybdis, not 
because of any pre-occupation of that name, which would 
have afforded a just reason, but because a different name 
Charybdea had been previously employed, which is no 
reason at all for cancelling Charybdis. Again, they would 
displace the earliest specific name cruciatus as inappro- 
priate, whereas, they argue, the name cruciferum, given 
by Fabricius, is in accordance with the great pale cross 
marked upon the carapace. It is true that Herbst pro- 
bably tortured the meaning of cruciatus, but it is quite 
clear that he intended it to bear the sense of cruciferum, 
and even if he had chosen to regard his crab as fixed to 
a cross instead of regarding the cross as fixed on the crab, 
it would not have justified any tampering with the name 
and the rights of priority. It is perhaps this species that 
suggested the story found in the old writers that on one 
occasion, to calm the sea, Xavier threw a crucifix into it, 
and that this was afterwards restored to him by a crab. 
Bathynectes, Stimpson, 1871, with a name that means 
‘the deep swimmer,’ is closely akin to Charybdis, but its 
antero-lateral margins have only five teeth, the hinder- 
most of which is very prominent, being twice as long as 
those which precede it. Thranites velox, of which in 
1876 and 1881 Professor Carl Bovallius gave a detailed 
description, illustrated by numerous excellent figures, has 
since been found to belong to Stimpson’s Bathynectes. 
The detailed description is in Swedish, the excellent 
figures are in a language which all but the blind can read 
with ease. The species has been identified with Stimpson’s 
Bathynectes longispina, 1871, but Canon Norman has 
recently made it probable that the priority rests with 
Portunus superbus, O. G. Costa, and that the name will, 
therefore, be Bathynectes swperbus, the species having ‘a 
range apparently co-extensive with the North Atlantic,’
