P. capitulo, valvarum duobus aut pluribus sub-rostro 

 verticillis instructo : valvis et pedunculi squamis rufo- 

 aurantiacis : squamarum verticillis densis symmetrice dis- 

 positis. 



Capitulum with two or more whorls of valves under the 

 rostrum : valves and scales of peduncle reddish-orange ; 

 the latter symmetrically arranged in close whorls. 



Maxillae with three tufts of fine bristles, separated by 

 larger spines ; segments in the first cirrus more than half 

 the number of those in the sixth cirrus ; caudal appen- 

 dages multi-articulate; filamentary appendages attached 

 to the prosoma. 



Coast of Peru, Payta, attached to wooden posts, according to Lesson : 

 Lobos Island, Peru, Mus. Cuming : West Coast of Mexico, Tekuantepec, on 

 an exposed rock, according to Hinds. 



The resemblance of this species is so close to P. cornu- 

 copia, that it is quite useless to do more than point out 

 the few points of difference. Valves of the capitulum 

 and scales of the peduncle, coloured (after having been 

 in spirits,) reddish-orange. In a specimen in which the 

 capitulum was 1*3 of an inch in length, there were three 

 whorls of valves below the carina ; in this large specimen 

 altogether there were about eighty valves ; in medium- 

 sized specimens, the number is about the same as in 

 P. cornucopia. The upper latus, (viewed internally,) has 

 an area about twice as large as that latus, which cor- 

 responds to the interspace between the carina and terga; 

 whereas in P. cornucopia the upper latus is only slightly 

 larger than this same valve. The apex of the basal in-
