LOPADORRHYNCHUS. 113 



the specimen in hand ; the cirrophores are attached at the base above and extend 

 ectad, large and subcyhndric, but falling much short of attaining the end of the 

 notopodium. The neurocirri are more conspicuous. They are attached near 

 the middle of the neuropodium; below the cirrophore each extends proximad 

 in a free, narrowly rounded lobe, and distad in a much longer, acutely acuminate 

 division which extends beyond the distal end of the neuropodium, but falls short 

 of the ends of the setae; the style of each neurocirrus is typically like an ovate- 

 lanceolate body bisected longitudinally and attached on the edge of section, 

 though sometimes it appears curved and almost crescentic. 



Locality. Galapagos Islands: Hood Island, Ripple Point. Sta. 4642 

 (lat. 1° 30' 30" S., long. 89° 35' W.). Depth 300 fms. Bottom broken shells 

 and Globigerina. Bottom temp. 48.6° F. 7 November, 1904. One incom- 

 plete specimen. 



Phyllodoce (?) sp. c. 



A fragment lacking the anterior end is 75 nam. long. Its greatest width is at 

 the anterior end where, exclusive of the parapodia, it measures 1.5 mm. It 

 narrows continuously cr.udad, being very slender in the posterior region. It con- 

 sists of approximately one hundred and forty-five somites. General color yellow. 



The venter is less strongly arched than the dorsum and is marked with a 

 neural furrow. Parapodia rather small. The notocirri are small, never exceed- 

 ing the distal end of the neuropodium, exclusive of its setae, and often clearly 

 shorter. Style ovate in outline, distally acute. The neurocirri are still smaller, 

 of a shape somewhat similar to that of the notocirri but obliquely truncate, 

 attached along edge of truncation. Setae and acicula colorless and transparent. 

 The aciculum emerges distally. 



Locality. Between Easter Island and the Galapagos: Sta. 4705 (lat. 15° 

 05' S. long. 99° 19' W.). 300 fms. to surface. Surface temp. 72° F. 28 Decem- 

 ber, 1904. One incomplete specimen.
