Trophosome. Stems with alternating branches, pinnately disposed; 
divided into internodes each of which usually bears a branch and three 
hydrothecae, two sub-opposite, the third axillar. Branches may themselves 
branch; divided into unequal internodes, each bearing several hydrothecae, 
sub-opposite, in pairs. Hydrothecae flaskshaped, adnate for more than half 
their length, apertures small, round, opening upward. 
Gonosome. Gonangia pearshaped, produced somewhat distally, end- 
ing with small round aperture.

Nutting’s treatment of Sertularia anguina Trask is unfor- 
tunate. To begin with, the figures of his Abietinaria anguina 
(Trask) are so far from typical of S. anguina Trask, judging 
either from Trask’s figures, Clark’s figures or all of my own 
material, some of which was collected at the entrance of San 
Francisco Bay, where Trask also obtained the species, that I 
suspect they really represent a distinct species. He says the 
are from Santa Barbara, Cal., and Ber- 
ee 
specimens he has seen 
ing Sea, and they all agree well with Dr. Clark’s description of 
Sertularia anguina var. robusta.’’ His figures, however, resemble 
Clark’s variety less than the typical S. anguina as shown by 
Clark’s own figures. Yet in his synonymy there appear S. 
anguina Trask, S. labrata Murray (a correct synonym) and S. 
anguina var. robusta Clark, but not the S. anguina Trask of
