The sea-temperature at 7 a.m. on the west of the Periya Paar Kerrai was 81 F., 

 and at 6 p.m. on the Vankali Paar was 82 - l F., the specific gravity as usual 

 being 1-023. 



We tow-netted during the day, and obtained on the surface numerous deep blue 

 Copepoda (Labidocera acuta) a deep blue Porpita and colonies of Compound Radiolaria 

 (Collozoum sp.) with black pigmented individuals, also Erich thus and other larval
