Doflein discusses the various species that had been assigned to the genus down 



to 1904. 



Mursia cristimanus, de Haan. 



1837. Mursia cristimanus, de Haan, Crust. Japonica, decas 3, p. 70. 



1839. Mursia cristimana, de Haan, Crust. Japonica, decas 4, p. 73, pi. E (mouth-organs). 



1900. Mursia cristimanus, Stebbing, S.A. Crust., part i. p. 22 (with synonymy). 



1904. Mursia cristimana, Doflein, Deutsch. Tiefsee-Exp., vol. vi. p. 38, pi. xvi. fig. 5-12, pi. xviii. fig. 1. 



To distinguish this species from M. armatus, de Haan, and its varieties or near 

 allies, Doflein relies especially on three characters : the front of the carapace produced 

 to a sharp central tooth ; the hind margin smooth, without teeth, only slightly 

 undulating and carrying a fine row of granules ; and thirdly, the under margin of the 

 chelae beset with coarse teeth, not exceeding eight or nine in number. With these 

 characters the Scotia specimen agrees. 



For determining the correct specific name the synonymy given by Dr Doflein 

 introduces some perplexity. He cites M. cristimana, Latreille, from Cuvier, 

 Regne animal, ed. 2, p. 39, 1829, but the name cristimana does not occur in that 

 work, so far as I can find, either on p. 39 of vol. iv. or elsewhere. On the other 

 hand, Doflein supplies a reference which I omitted in 1900, namely, Mursia cristata, 

 Milne-Edwards, in Atlas zu Cuvier, Regne animal, ed. 3, Taf. xiii. fig. 1 and la, to 

 which he attaches the date 1836. If that date can be depended on, the name of the 

 species should be cristatus instead of cristimanus, since the latter is not earlier 

 than 1837, so far as known. It is true that in 1837 Milne-Edwards gives a reference 

 to pi. xiii. of the 3rd edition of the Regne animal, but it does not follow that the 

 undated plate had been published a year earlier, so that de Haan's cristimanus may 

 still hold its ground, till proof is forthcoming of the true date of publication for 

 pi. xiii. in the 3rd edition of the Regne animal (see additional note, p. 307).
