Medusa of the Philippines and of Torres Straits. 171 



bell is dull milky yellow and the flexible parts of the tentacles are pink. In 

 common with other Cubomedusae it comes to the surface when mature, and 

 is then abundant in harbors. The young usually remain in deep water at or 

 near the bottom. 



Carybdea alata var. grandis Agassiz and Mayer.

The bell of this medusa becomes 230 mm. high, but the largest specimen of 

 this cruise was obtained by the Albatross in Borneo and is only 166 mm. high. 

 This tropical Pacific form may be distinguished by its short, wide-flaring 

 pedalia and by having only 1 or 2 median eyes upon each sense-club and no 

 lateral eyes. When young, however, there are 2 large median and 2 small 

 lateral eyes, but the latter appear to fuse later with the median eyes. There 

 are 24 velar canals, which are short, branched, and non-anastomosing. C. 

 moseri is probably only a young stage of this medusa. In C. alata there are 6 

 eyes in each sense-club, and the pedalia are longer and narrower than in the 

 large variety grandis. 



The dimensions and characters of the two largest of the three specimens 

 found by the Albatross are as follows:

GENERIC CHARACTERS. 



Carybdeidae with 4 interradial, branching pedalia which give rise to a 

 number of tentacles. Four wide perradially situated stomach-pockets in the 

 subumbrella, each of which gives rise to finger-shaped, unbranched, hernia- 

 like pouches which project into the bell-cavity. Wide, marginal pouches and 

 numerous canals in the velarium. 8 leaf-shaped gonads.

44 specimens of this medusa were collected by the Albatross from the 

 Philippines, but not one seems to be mature. 



Light (1914) found this medusa at Culion Bay, Culion, and at Palawan and 

 thus it ranges widely in the Philippines. Light's specimens were larger than 

 those found by the Albatross, being at least 200 mm. in diameter and usually 

 with 7 tentacles to each pedalium. The tentacles are 1.5 meters or more in 

 length and have lavender-colored bands of nematocysts. Light reports that
