Distribution. — T3^pe specimen (IJ.vS.N.M. No. 9102) from Albatross 

 station D5670 in 1.181 fathoms (2,160 meters), Macassar Strait, 

 bottom temperature 38.2° F. (3.4° C). It also occurred at D5622, 

 in 275 fathoms (503 meters), between Gillolo and Makyan Islands 

 and at D5619 in 435 fathoms (796 meters), Molucca Passage. At 

 this last station it was very abundant, so much so that it might 

 almost be called a DendropJirya attenuata bottom, as this made up 

 the great mass of the washed material at this station. 



Dendrophyra attenuata. — Material examined. 



Genus HALIPHYSEMA Bowerbank, 1862.

 pi. 28, figs. 5, 6. 



Description. — Test elongate, tapering, with numerous constrictions 

 as though segmented; wall arenaceous, with many included frag- 

 ments of sponge spicules and with a crown of elongated spicules about 

 the aperture; basal end with a sort of expanded portion like a pro- 

 loculum, also made up largely of broken spicules; aperture terminal, 

 circular, surrounded by the crown of erect spicules. 



Length about 10 mm. 



Type spedmen. — Cat. No. 8464, U.S.N.M., from Albatross station 

 D5630, south of Patiente Strait, Dutch East Indies, 569 fathoms 

 (1,081 meters). The species was very common at this station, but 

 was not met with elsewhere in the dredgings. 



The spicules throughout the test except at the apertural tip are 

 broken fragments, but about the aperture there are elongate spicules 

 not entire, but so placed that they rise up above the aperture like a 

 crown. 



Haliphyseyna catenulata — Material examined.
