3.28 POLLICIPES SERTUS. 



cequante, superficiei interna altitudine latitudinem plus 

 duplo superante: pedunculi squamis inaqualibus, non sym- 

 metritis: verticillis longiuscule distantibus. 



Capitulum with one or more whorls of valves under the 

 rostrum : upper pair of latera only slightly larger than the 

 lower latera : membrane covering the valves (when dried) 

 dark reddish-brown : rostrum half as long as the carina, 

 with its inner surface more than twice as high as broad : 

 scales of peduncle of unequal sizes, unsymmetrically 

 arranged in rather distant whorls. 



Maxillse with two tufts of fine bristles, separated by 

 larger spines : caudal appendages uniarticulate : fila- 

 mentary appendages none. 



New Zealand; Mus. Cuming. 



Capitulum, much flattened, broad, sub-triangular. 

 Valves exceedingly various in number; in the largest 

 specimen with a capitulum foths of an inch high, and 

 Toths of an inch wide, there were only thirty-one valves, 

 and these formed only a single whorl under the carina 

 and rostrum; whereas, in another specimen, which was 

 barely Toths of an inch in length, there were fifty-two 

 valves, and these formed two or three distinct whorls under 

 the carina. Scuta, terga, carina, and rostrum, much 

 larger than the other valves. All are moderately thick, 

 placed rather distant from each other, covered with thick 

 membrane which abounds with tubuli, arranged in rows ; 

 surface apparently smooth, but with a very high power, 

 extremely minute spines can be seen at the extremities of 

 almost all the tubuli. Little bunches of reddish fibrous 

 matter are imbedded in the membrane, like tufts of sea- 

 weed floating in water. 



Scuta, triangular, basal margin curved, protuberant; 

 the upper part of the tergo-lateral margin is, also, slightly 

 protuberant. 



Terga, large, oval, basal angle broad, square; lower 

 part of carina! margin straight, upper part narrowed in; 

 the apex is covered with membrane and projects freely.
