HYDROMEDTJSiE. 
Genus SOLMARIS Haeckel. 
Solmaris Haeckel, Syst. der Medusen, p. 355, 1880. 
Generic characters: Solmaridse with a numerous and variable number of tentacles alternating with 
the equally numerous marginal lappets. Stomach a simple lenticular cavity, without pouches extend- 
ing into the lappets. Gonads more numerous than the lappets and appearing as a ring of wart-like sacs 
in the subumbrella wall beyond the periphery of the stomach. 
Solmaris insculpta, new species. 
PI. in, figs. 8, 9. 
Specific characters: The bell is about f as high as a hemisphere and, in large specimens, is about 
24 mm. in diameter. The rim of the bell consists of 14 lappets, the adjacent edges of which are joined 
by a velar web. The exumbrella of the bell is sculptured in high relief. A prominent ridge extends 
down the middle line of each lappet, and this median ridge is flanked by two others which extend 
down near the edges of the lappet. The valleys between the ridges are well marked, and the ridges 
themselves are rendered quite conspicuous by violet pigment which extends along their crests. 
There are 14 relatively stiff tentacles which alternate with the lappets, arising from the sides of 
the bell at a zone about one-quarter of the distance from the rim of the bell to the apex. The ento- 
derma 1 cells of these tentacles are disk-like and their entodermal cores project inward to the edge of 
the stomach. The tentacles are all of the same size, and are a little longer than the bell radius. 
Preservation in formalin had destroyed the otoliths, but it appears that there are three marginal 
sense organs to each lappet, or 52 in all. 
The stomach is a flat lenticular cavity, and the mouth a simple round opening. There are 42 
oval, pouch-like gonads arranged in a circle around the edge of the stomach. Of these gonads 14 occupy 
intertentacular radii, while the remaining 28 flank the sides of the tentacle bases. The gonads are 
regularly spaced in a circle at the periphery of the stomach; not grouped into more or less separate 
clusters as in Solmaris godeffroyi Haeckel, of Samoa. Moreover S. godeffroyi lacks the complex sculp- 
turing of the exumbrella seen in S. insculpta, and. there are but 24 gonads, arranged in 8 sets of 3 each 
(see Haeckel, 1879, Syst. der Medusen, p. 355, taf. xix, fig. 2). 
Specimens of S. insculpta preserved in formalin show gonads of a faint purplish brown color, while 
the sculptured ridges of the exumbrella are violet. 
Forty specimens were obtained by the Albatross among the Hawaiian Islands, all being found on 
the surface. Small individuals have 12 or 13 tentacles, but the normal number in large specimens 
appears to be 14. Type no. 21799 U. S. National Museum.
