Siphonophora of Scottish National Antarctic Expedition. 19 
The occurrence of Physaliz has been recorded in the Zoological Log 
at stations 42, 53, 57, 60, 72,78, 82, 83, 95, 97, 508, 509, 525, 529, 530 
and 531. 
The five young Physaliz taken in the tow-net at Station 30 have well 
developed pneumatophores 3, 3:5, 4,6 and 12 mm. in length respectively, 
that of the largest specimen exhibiting a comparatively large polythalamic 
jane, 2, 
erest. Although not well preserved, several small siphons and a larger 
central one could be distinguished. The two specimens from Station 81 
are very well preserved. The length of their pneumatophores measures 
roughly 9 and 10°5 em., the breadth 4 and 4 cm., and the thickness, including 
crest, 5 and 4'5 cm. respectively. The crest and cormidia are well developed. 
Each specimen has about ten tentacles, the longest of which is in one 
case 30 cm., and in the other 24 cm. The example recorded from Table 
Bay (Station 478) is not in a very good state of preservation, the remnants
