BIOLOGICAL RESULTS OF LAST CRUISE OF CARNEGIE 



Siriella distinguenda, H. J. Hansen 



S. distinguenda, Hansen, 1910 



OCCURRENCE 



Region of Samoa, April 1929, surface, thirty adults 

 of both sexes. 



DISTRIBUTION 



This species has only been recorded once previous- 

 ly, by Hansen, from three stations in the East Indian Ar- 

 chipelago. The present record, therefore, indicates a 

 considerable extension eastward of its known distribu- 

 tion. It would appear to be a shallow -water and harbor 

 species. 



Genus HENOSIRIELLA, Hansen, 1910 

 Hemisiriella pulchra, H. J. Hansen 

 H. pulchra, Hansen, 1910 



OCCURRENCE 



Region of Samoa, April 1929, surface, one male and 

 fourteen females. 



Moored in Guam Harbor, May 1929, surface townet, 

 8.10 to 9.50 p.m., light in net mouth, one female. 



DISTRIBUTION 



This species has only been recorded once before, 

 namely by Hansen from six stations in the East Indian 

 Archipelago. 



Hemisiriella parva, H. J. Hansen 



H. parva, Hansen, 1910 



H. parva, Colosi, 1918 and 1920 



H. parva, Zimmer, 1918 



H. parva, Tattersall, 1922 



OCCURRENCE 



Station 95, latitude 08° 43' south, longitude 170° 56' 

 west, 100 m, April 24, 1929, one immature male. 



Station 100, latitude 08° 05' north, longitude 178° 48' 

 west, 50m, May 4, 1929, one immature male. 



DISTRIBUTION 



This species has been recorded from four stations 

 in the East Indian Archipelago (Hansen, 1910), Bay of 

 Bengal (Hansen, 1910), Java (Zimmer, 1918), Indian 

 Ocean (Colosi, 1918 and 1920) and the Andaman Islands 

 (Tattersall, 1922). The present records, therefore, ex- 

 tend its known range considerably eastward. 



Subfamily GASTROSACCINAE, Norman 



Genus ANCHIALINA, Norman and Scott 



Anchialina flemingi, n. sp. 



OCCURRENCE 



Between stations 89 and 90, latitude 17° 04' south, 

 longitude 152° 58' west, surface, March 23, 1929, one 

 adult male. 



Region of Samoa, April 1929, surface, two immature 

 specimens. 



DESCRIPTION 



Carapace, in the male, produced into a long triangu- 

 lar, acutely pointed rostral' plate extending forward as 

 far as the distal margin of the first joint of the antennu- 

 lar peduncle (fig. la, p. 72). 



Eves small, about as broad as the antennular pedun- 

 cle, pigment light brown. 



Antennular peduncle stout, third joint longer than the 

 second. 



Antennal scale (fig. 2a, p. 72) small, not extending 

 very much beyond the distal end of the first joint of the 

 antennular peduncle and shorter than the second joint of 

 the antennal peduncle; twice as long as broad; outer mar- 

 gin entire, terminating in a short spine beyond which the 

 setose part of the scale is prolonged for about one quar- 

 ter of its length; terminal joint distinctly articulated; 

 antennal peduncle with the second joint large and stout, 

 longer than the antennal scale, and about twice as long 

 as broad. 



First thoracic limbs (fig. 3a, p. 72) with the endopod 

 very stout, nail very long and stout, longer than the sixth 

 joint. 



Second thoracic limbs (fig. 3b, p. 72) with the second 

 joint of the endopod massive, fifth joint expanded on its 

 inner margin to form almost a right-angled projection, 

 the margin between the projection and the sixth joint 

 with six or seven minute teeth; sixth joint not expanded; 

 nail long. 



Pseudobranchial lamellae of the male pleopods not 

 bilobed, more or less triangular in shape with the inner 

 angle broadly rounded, outer angle more narrowly round- 

 ed and armed with a single seta. 



Exopod of the third pair of pleopods of the male (fig. 

 3c, p. 72) at least one and a half times as long as the en- 

 dopod, nine-jointed, each joint with a seta on both the in- 

 ner and outer corner; last four setae on the outer margin 

 and the last three on the inner margin modified, much 

 shorter and stouter than the other setae, with minutely 

 hooked tips. 



Sixth segment of the abdomen one and a half times as 

 long as the fifth. 



Telson (fig. lb, p. 72) longer than the sixth segment 

 of the abdomen, three times as long as broad at the 

 base; cleft one sixth of the length of the telson in 

 depth, and armed on both margins with a closely set row 

 of saw-like teeth; lateral margins armed throughout their 

 length with about thirty-three spines arranged in groups
