While M. E. L. Bouvier appears to be certainly right in iden- 

 tifying granulosa with verrucosa, as suggested with less confidence 

 by various other authors, among whom Dana himself may almost 

 be reckoned, it must, I think, be conceded that the name granulosa 

 takes precedence. No doubt its priority depends on the figures in 

 Jacquinot's Atlas, but they give much more information than many 

 an accepted specific description. There are cases in which authors 

 have evidently described species only from figures ; Lucas in some 

 instances acknowledges that he had only the figures in Jacquinot's 

 Atlas, and not the corresponding specimens, to guide him. It 

 would be an absurdity to allow authority to a description made 

 from a figure, but to discredit the figure itself. 



In his synoptic table of the eight species of Paralomis above 

 mentioned, Bouvier separates verrilli, granulosa, formosa, and 

 aspera from the other four, as having the rostrum without any 

 rudiment of projection below. He unites verrilli and granulosa 

 by the common characters : " Acicle long triangular, acute, armed 

 outside with 3 or 4 spines ['? teeth] ; carapace covered with verru- 

 cosities or very low and very obtuse tubercles ; chelipeds unequal ; 

 walking-legs very compressed." He separates granulosa by the dis- 

 tinctive characters : " The right cheliped reaches considerably beyond 

 the base of the finger of the first walking-leg; it is furnished on the 

 inner margin of the antepenultimate joint with a salient crest 

 armed with 5 or 6 spines [teeth]. Carapace verrucose, except in the 

 large adults, in which it becomes tuberculose. The fourth joint 

 of the walking-legs is compressed from front to rear, the three 

 following joints from above to below. No unpaired gastric spine 

 [tooth]." The species indica and investigatoris of Alcock and 

 Anderson, added to the genus in 1899, both have the walking-legs 

 longer than the chelipeds, and in indica the latter have the wrist 

 not expanded to a foliaceous lobe. 



The distinction drawn between warts and tubercles is not very 

 easy to appreciate. Of Jacquinot's specimen, only 12 mm. long 

 by 10 broad, Lucas says that the carapace is "entirely covered with 

 little, close-set tubercles, flattened and granular at the top." Miers 

 says of a very young example in the British Museum, " the gran- 

 ulated and wart-like tubercles of the carapace are closely crowded
