198 EXPEDITION OF THE - ALHATROSS;' kS'.)!)-l900. 



No record of these two tow-net stations can be found From the nearest 

 record it would seem that the "Albatross" was hi the vicinity of the 

 Galapagos Islands.' There are a large number of the aggregate generation 

 in this collection. 



Stn. 7 A.A., Sept. 1, 1S99, Lat. N. 18^ 19', Long. W. 134^^ 57', surface 

 temp. 76°. A number of specimens of the solitary generation were taken 

 at the surface, 8 i\ m. 



Stn. 12 A.A., Sept. 4, '99, Lat. N. 12 07', Long. W. 137' 18'. Surface 

 temp. 81°. Four large specimens of the aggregate generation Avere collected 

 between a depth of 150 fathoms and the surface. Two of them measure 

 6.5 cen. in extreme length and the smallest measures 4.5 cen. The test 

 over the nucleus is much thickened and ridged, and the posterior processes 

 show a tendency to become prismatic. Variations of this kind are men- 

 tioned by Herdmann as occurring in large specimens collected in the South 

 Pacific by the " Challenger." 



Stn. 14 A.A., Sept. 7, 1899, Lat. N. 6° 41', Long. W. 137°, surface temp. 

 82'. One specimen of the solitary and three of the aggregate generation 

 were taken on the surface at 8 P. M. 



All "of the aggregate generation have the anterior and posterior processes 

 very short and bifurcated. Two of them have a short process at the level of 

 the branchial orifice on the left side. 



Stn. 15 A.A., Sept. 8, 1899, Lat. N. 4° 35', Long. W. 136° 54', surface 

 temp. 79°. Two of the solitary and four of the aggregate generation were 

 collected on the surface at 8 v. Ji. 



All are more or less angular. Those of the aggregate generation have 

 the serrate ridges strongly developed, and the test much thickened over 

 the nucleus. 



Stn. 31 A.A., Sept. 19, 1899, Lat. S. 12° 20', Long. W. 144° 15', .surface 

 temp. 80\ Two specimens of the solitary generation were taken on the 

 surface, 7 v. m. 



Stn. 89 A.A., Oct. 14, 1899, Lat. S. 16° 03.5', Long. W. 145° 43', surface 

 temp. 80'. About one mile N. 28° W. of north entrance to Fakarava. Two 

 specimens of the aggregate generation were taken between 350 fathoms and 



the surface.
