LYTOCARPUS BALEI Nutting 



Lytocarpus balei Nutting, Hydroids of the Hawaiian Islands, 1905, p. 954, 

 pi. 13, figs. 7 and 8. 



The specimens secured by the Albatross agree fairly well with the 

 type specimen of this species and show the strong septal ridges in 

 the hydrocladia. The Albatross material, however, differs in having 

 relatively longer supracalycine nematophores. The gonosome is not 

 present.

Genus THECOCARPUS Nutting 



Stechow in 1920 relegates the genus Thecocarpus to synonymy and 

 replaces it with Lytocarpia of Kirchenpauer (1872). But Bedot 

 (1921) rejects Stechow's arguments and reaffirms the validity of 

 Thecocarpus Nutting. The present writer believes that the position 

 of Bedot is the stronger and had written out a defense of the genus 

 Thecocarpus before Bedot's work came to hand, but prefers to allow 

 the validity of the genus to be maintained by Bedot. 



THECOCARPUS BALEI, new species 



Plate 47, figs. 1, 2 



Trophosome. — Colony plumose, specimen unbranched, 10 cm. high 

 and with a spread of 4 cm., fascicled almost to tip, straight, without 

 evident internodes. Hydrocladia alternate, close-set, borne on one 

 side of the stem, all springing from the same tube (hydrocladiate 

 tube) of the fascicled stem, divided into regular nodes by oblique 

 internodes, each of which bears a hydrotheca. Hydrothecae cup- 

 shaped, rather small for this genus, about one and one-quarter as 

 deep as wide; margin slightly everted, somewhat undulating on the 

 sides, but without evident teeth except a median anterior one which
