As regards form, the tentacles show a.number of types, of which the most important are (I) filiform, i.e.
(b) Tentacles with a bilateral arrangement, branched tentacles in addition to simple filiform ones; type of Branchiocerianthus.
Trophosome, polyps with two whorls of tentacles, the lower filiform, the upper capitate; gonosome, free medusae, with tentacles solid and branched.
Trophosome, polyp with filiform tentacles in three or four whorls.
Trophosome, polyps with scattered filiform tentacles; gonosome, medusae or gonophores, the medusae with hollow tentacles.
"He saw that they increased in size, divided, and became full of filiform spores, then ruptured and poured out their multitudinous progeny into the bodycavity of their insect host.
Bathanalia, from x, Filiform appendage (?
Of particular zoological interest in this connexion is a Ceylonese genus Dyscritina, in which the cercopods are long, many-jointed and filiform during the early stages of growth, and only assume at the last moult the forcipate structure characteristic of the family.
- These singular crustaceans have long soft flexible bodies, the eyes stalked and movable, the first antennae small and filiform, the second lamellar in the female, in the male prehensile; this last character gives rise to some very fanciful developments.
As in all Arachnida there is only a single pair of appendages in front of the mouth, and these were onebranched, long and filiform and acted as antennae.
500 times.) A branched filiform thallus of Stigonema with the hyphae of the fungus growing through its gelatinous membranes.
Usually the metal is arborescent, dendritic, filiform, moss-like or laminar.
B, Upper and filiform and fringed surface of same; valves closed.
Amphicarpum, native in the southeastern United States, has fertile cleistogamous spikelets on filiform runners at the base of the culm, those on the terminal panicle are sterile.
Lankester (5) has shown (and his views have been accepted by Professors Korschelt and Heider in their treatise on Embryology) that the limb of the lowest Crustacea, such as Apus, consists of a corm or axis which may be jointed, and gives rise to outgrowths, either leaf-like or filiform, on its inner and outer margins (endites and exites).
This may be filiform or brush-like or lamellate when it is an antenna or palp; a simple spike (walking leg of Crustacea, of other aquatic forms, and of Chilopods and Diplopods); the terminal joint flattened (swimming leg of Crustacea and Gigantostraca); the terminal joint provided with two or with three recurved claws (walking leg of many terrestrial forms - e.g.
The rami may be flattened for swimming, when it is " a bi-ramose swimmeret," or both or only one may be filiform and finely annulate; this is the form often presented by the antennae of Crustacea, and rarely by prae-oral appendages in other Arthropods.
