576 " THETIS " SCIENTIFIC RESULTS. 



plumosa, pacifica, californica^ coeca, lohata, and in the same year 

 Mr. Arthur Pearse described Ampelisca holmesii. 



AMPELISCA PUSILLA, Sars. 



Station 57. 



Ampelisca pusilla, Sars, Crust. Norway, i., 1891, p. 181, pi. Ixiii., 

 fig- 2. 



It may seem improbable that this little species from the high 

 north should be found in Australian waters, and I was inclined 

 to call the single " Thetis" specimen pcenepusilla, but the differ- 

 ences scarcely justify specific separation. There appear to be 

 ocular lenses present, which are wanting in the northern form. 

 In the fifth peraeopods the hind margin has a smoother curve 

 than that shown in either of the figures given by Sars. Each 

 lobe of the telson has a single apical spinule instead of the " two 

 small marginal spinules near the tip," spoken of by Sars. 



Locality. — Off Wata Mooli, 54-59 fathoms

Seven genera are defined for this fsamily in "Das Tierreich," and 

 to that number Chevreux, in 1908, added the new genus 

 Jouhinella. Three of the genera are represented in Australian 

 waters.
