Trachymedusae: Rhopalonematidae
Zootaxa, 1981A new species of deep-sea jellyfish, Crossota millsae (Cnidaria: Hydrozoa: Trachymedusae: Rhopalonematidae), is described from the North Pacific Ocean off California and Hawaii. Discrete depth sampling showed this species lives at depths below 1000 meters in both geographic locations. The species is more abundant off California than off Hawaii.

Pharmacology of the radial neuromuscular system of Liriope tetraphylla (Hydrozoa, Trachymedusae)
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1988Abstract 1. 1. In an attempt to analyse the cholinergic pre-synaptic modulatory hypothesis (Scemes and Mendes, 1986), the effects of magnesium and calcium ions and of cholinergic agonists and antagonists on the behavior of Liriope tetraphylla were studied. 2. 2.

Journal of Experimental Marine Biology and Ecology, 1996
Abstract The osmoregulatory capability and swimming behavior of Liriope tetraphylla (Chamisso and Eysenhardt) were analyzed under hyposmotic conditions. These hydromedusae are shown to be osmoconforming animals that are not able to maintain constant osmotic and ionic concentrations of their body fluids when exposed to anisosmotic media.

Dermatology, 2000
Multiple stages of <i>Liriope tetraphylla</i> caused paresthesias leading to chafing and excoriations in swimmers along the Southern Uruguayan and Northern Argentinean Atlantic coasts. These episodes appear seasonally in the summer and affect groups of bathers in shallow water (1–3 m).

Polar Biology, 1998
The trachymedusa Ptychogastria polaris Allman, 1878 has been identified in seabed photographs from high-Arctic shelves and upper continental slopes off Northeast Greenland and in the northern Barents Sea. It was found to be a common epifaunal element, being present at 34 of 57 stations in 40- to 495-m depth and at 7 of 11 stations in 70- to 330-m depth,

Trachymedusae and Narcomedusae of South-east Australian Waters
Marine and Freshwater Research, 1955Thirteen species of Trachymedusae and seven of Narcomedusae are recorded from south-east Australian waters, where both orders were previously unknown. Eight Trachymedusae and four Narcomedusae are new records for the entire Australian region. Additions are made to the descriptions of some species.
