214 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.21 



scription above. The small size of the propodal teeth as compared to those 

 of T. marginatus, again a reversal of the situation presented in Rathbun 

 (1925, p. 162, key only; diagnoses and descriptions are correct), is 

 noticeable, as is the fourth marginal tooth, which is postlateral in position. 



Although the ranges of the two South Pacific species of Taliepus 

 overlap in southern Peru and northern and central Chile, T. marginatus 

 finds its southern limit in the vicinity of Talcahuano, whereas T. dentatus 

 continues to Magellan Strait, and perhaps to the tip of South America. 



The species first made its appearance as an article of food in the 

 markets of Valparaiso and Santiago about 1915, according to Porter 

 (1925).

Type: Female holotype, originally deposited in the Bell Museum, not 

 extant. 



Type locality: In place of the original designation, "Ad oras Brasil- 

 iae," where the female holotype was purportedly collected by Miller, and 

 for reasons stated under Remarks below, the type locality is corrected to 

 Valparaiso, Chile, where a large male specimen was collected by Hugh 

 Cuming (cf. Bell, 1836, p. 63). 



Localities subsequently reported, with collectors: Peru: "Peru" 

 (Aurivillius) ; Independencia Bay and Mollendo, R. E. Coker (Rath- 

 bun, 1910). Chile: "Chile," Novara (Heller), (A. Milne Edwards), 

 Ackerman (Ortmann) ; Iquique, Cavancha, and Guaiacan (Lenz) ; Cal- 

 dera, Capt. Putnam (Rathbun, 1925) ; Valparaiso, J. D. Dana (Rath- 

 bun, 1894); Talcahuano, Alert (Miers, 1881). 



Atlantic analogue: None. A Pacific austral species, and the Southern 

 Hemisphere counterpart of Taliepus nuttalli (Randall).
