but not of the half-grown, medusa. The velum is well developed. The 4 radial-canals and 

 ring-canal are slender and simple. The manubrium is spindle-shaped and shorter than the 

 depth of the bell-cavity. In the halt-grown medusa there is a short conical peduncle, but this 

 was not seen by Maas in his large specimens. 



The mouth is at the extremity of a bluntly pointed, conical neck, and is a simple round 

 opening. 32 or more short, slender, filiform, unbranched oral tentacles arise from a zone 

 above the mouth. Each oral tentacle is solid and ends in a knob-like cluster of ncmatocysts. 



1 he gonads are found on the upper interradial sides of the stomach and appear as a pair 

 of longitudinal swellings in each of the 4 interradii. They are not developed on the 4 radial 

 lines of the stomach. The eggs protrude over the surfaces. 



In the formalin specimens studied by Maas, the gonads were yellow, the axial entoderm 

 of the stomach dark-red, as were also the entodermal parts of the tentacle-bulbs. There is 

 some green pigment in the ectoderm of the tentacle-bulbs. In the immature specimens from 

 Fiji, studied from life by Dr. Agassiz and his assistant, the entoderm of the outer part of the 

 manubrium and of the tentacle-tips was green, while there was red pigment in the axial part of 

 the stomach and in the tentacle-bulbs and adjacent parts of the 4 radial-canals. In the young 

 specimens from Fiji the oral tentacles ranged from 4 to id, while in those found by Maas in 

 the Malay Archipelago, they ranged from 8 to 32. 



Found in abundance on the surface among the Fiji Islands in November to January. 

 Maas found numerous specimens in the Siboga collection from the Malay Archipelago, 

 Sulu, Damar, Daiam. Sabuida, Gisser, Mampa Straits, and Saleyer; and from Amboma, 1906.

Umbrella about 3.5 mm. in width and height. Somewhat bell-shaped with fairly thick 

 walls. 4 marginal, long tentacles with very large, spear-head-shaped, basal bulbs one-third as 

 lung as the bell-height. The ectoderm of the tentacles is thickly crowded with nematocysts. 

 The entoderm of the tentacles and basal bulbs is pigmented. Velum narrow. 4 wide, straight 

 radial-canals. Stomach about as wide as long placed upon a short peduncle and extending 

 a little more than half-way down the cavity of the bell. A row of 50 to fto short, equalh 

 spaced oral tentacles, each ending in a knob of nematocysts. Gonads form 4 (perradial ?) 

 swellings extending the entire length of the stomach. Color ( ?) Coast of Ceylon; Chilaw 

 Paar, and Cheval Paar; March to November.

The name l)\<snitirf>litis<i was first used In Philippi, 1^42, in his description ol I). <on- 

 <-/i/t olt/, a hydroid polyp which may have been either a Podocoryne or a Hydr actinia in the 

 modern sense. In 1846, Sars described a closely related, medusa-bearing hydroid under the 

 name Podocorvne cornea. The name Dysmorphosa was first applied to the free medusa by A. 

 Agassiz, 1865. The great majority of authors have included both the hydroid and the tree 

 medusa under the generic name I'oJm <>i \n< . In the absence of proof as to whether Philippi's 

 hydroid develops medusae or not, we are unable to decide with certainty which name should 

 stand, but there is no probability that Philippi's hydroid will ever be determined and we niav 

 avoid confusion by considering it obsolete.
