in T. diademata, the manubrium, gonads, and tentacles being faint yellow. Found between 

 San Diego and Monterey, California, from 50 to 200 fathoms. 



Torrey proposes to separate the old genus Tuiropsis. He would retain the name Tiaropsis 

 to describe all forms having tentacles of only one sort, and Tiaropsidium to designate medusae 

 having some well-developed and some rudimentary tentacles. A realization of the constant 

 difficulty in distinguishing between rudimentary and merely young and undeveloped tentacles 

 prevents me from accepting these distinctions. 



Phialidium languidum (see page 269). 

 Phialidium loma, Torrey, 1909, University of California Publications, Zool., vol. 6, p. 22, fig. 8. 



I can not distinguish this California medusa from the common Phialidium languidum 

 of the Atlantic coast of North America. 



Genus Phialopsis Torrey, 1909. 

 Phialopsis, Torrey, 1909, University of California Publications, Zool., vol. 6, p. 23. 



The type species is Phialopsis die gen sis of San Diego, coast of California. The genus is 

 similar to Phialuctum but with cirri upon the bell-margin. 



Phialopsis diegensis Torrey. 

 Phialopsis diegensis, Torrey, 1909, University of California Publications, Zool., vol. 6, p. 23, fig. 9. 



Bell flat, 23 mm. wide, moderately thick walled. 16 to 28 well-developed tentacles, 5 to 



9 rudimentary tentacles between each two long tentacles. Cirri somewhat more numerous 



than the rudimentary tentacles. 60 to 100 lithocysts each with 2 to 6 concretions. Manubrium 



short with cruciform base and broad, fluted lips. Gonads linear on outer three-fourths of the 



4 radial-canals. Color ( ?) Found at San Diego, California, May to July, from the surface 



to a depth of 160 fathoms. 



Eucheilota bakeri. 



Phialium bakeri, Torrey, 1909, University of California Publications, Zool., vol. 6, p. 21, fig. 7. 

 Clytia bakeri, Torrey 1906, Ibid., vol.2, p. 323. 



This medusa is set free from the hydroid described by Torrey, 1904 (Ibid., vol. 2, p. 16), 

 as Clytia bakeri. When set free the bell is oval, thin-walled, with 2 well-developed and 2 

 small, immature tentacles. 4 radial-canals. 2 gonads, 4 lithocysts. Cirri flank the basal- 

 bulbs of the large tentacles. The 2 ovate gonads are upon the middle points of the 2 radial- 

 canals in the radii of the long tentacles. The hydroid is found attached to clams and other 

 mollusks upon sandy flats along the coast of California from Oceano to San Diego. The 

 mature medusa is unknown. The young medusa recalls the condition seen in Eucheilota 

 dipleuron from the North Carolina coast. 



Eutima brownei. 

 Eutimalphes brownei, Torrey, 1909, University of California Publications, Zool, vol. 6, p. 25, fig. 10. 



Bell nearly spherical, evenly rounded, thick at apex, and about 15 mm. in diameter. 

 About 130 short tentacles with bulbous bases, each flanked by I to 3 pairs of long, slender 

 cirri. No marginal papillae. 8 adradial lithocysts with 6 to 13 concretions in each. Manu- 

 brium short and broad with 4 wide, frilled lips. Peduncle wide, conical, and about as long 

 as the depth of the bell-cavity. Gonads 4 narrow bands upon the subumbrella lengths of the 4 

 radial-canals. Gonads with straw-yellow entoderm and turquoise-blue ectoderm. Tentacles 

 with red-brown entoderm and turquoise-blue ectoderm. Found on the surface in June and 

 July at San Diego, California. 



Only 10 out of 90 specimens possessed cirri. During growth the gonads extend outward 

 along the radial-canals. 



Eutima campanulata (?) (see page 302). 



Octorchandra orientalis, Hartlaub, 1909, Zoologische Jahrbiicher, Abth. Syst., Bd. 27, p. 456, taf. 20, fign. 11-15. 



Hartlaub states that this medusa from Djibuti, east coast of Africa, is closely allied to 

 Haeckel's 0. germanica of the German coast, but differs in its large bell, thick gelatinous 

 walls, and relatively short peduncle. In the African medusa bell is 15 mm. wide and peduncle
