658 PATAGONIAN EXPEDITIONS: ZOOLOGY. 



Distribution. Tierra del Fuego ; Straits of Magellan ; northward to 

 Chiloe. Shallow water. 



PARALOMIS White. 



PARALOMIS GRANULOSA (Jacquinot). 



1891 P. g. A Milne-Edwards in: Miss. Cap Horn, v. 6, p. 20. 

 1896 P. verrucosa Bouvier in : Ann. Sci. nat, ser. 8, v. i, p. 26. 

 1900 P. gramtlosa Stebbing in : Proc. Zool. Soc., p. 532. 



Localities. Punta Arenas, 4^39; Cape Fairweather, 2 J 1 jun. 



Distribution. Falkland Islands ; Tierra del Fuego ; Straits of Magellan. 

 On the eastern Patagonian coast this species has been found as far north 

 as Bahia Blanca (Prov. of Buenos Aires), 38 42' S. (Berg, 1900), while 

 on the western coast it does not seem to go beyond Trinidad Channel 

 (50 S.). 



Remarks. According to Stebbing, the specific name of P. granulosa 

 has to supersede that of P. verrucosa, having been published (on Jacqui- 

 not's plate) not later than in 1847, while L. verntcosa of Dana was pub- 

 lished in 1852. 



The two young individuals from Cape Fairweather correspond closely 

 to L. verrucosa of Dana (1852, p. 428, pi. 26, f. 16). Both have the 

 length of the carapace, 27 mm. The specimens from Punta Arenas are 

 all larger, and most of them seem to be adult ; the smallest, a soft shell 

 female, is 61 mm. long (carapace only), and this one is intermediate in 

 sculpture between the young and adult specimens ; the tubercles of the 

 surface are more crowded than in the latter, but a little more distant from 

 each other than in the former. The same is true of the granulations of 

 these tubercles, they being less developed than in P. verrucosa, but more 

 strongly than in the adult individuals. Length of adult males : 92, 101, 

 107 mm.; of an adult female: 72 mm. 



This leaves no doubt as to the identity of P. granulosa and verrucosa, 

 the former being only the young stage of the latter, as already Bouvier 

 (1896) maintained.
