RF2JP9CB9–Seabed marine invertebrates: Sea Cucumber (Cucumaria planci), Violet or Purple Sea Urchin (Sphaerechinus granularis), Red Starfish (Echinaster sepositus) and Spiny Starfish (Marthasterias glacialis). Depicted in a rare early 1900s German chromolithograph print of a painting by wildlife artist, Paul Flanderky (1872-1937). It helped to illustrate the (1911-18) 4th edition of Brehms Tierleben (Brehm’s Animal Life).

RMPFJN4G–. The Danish Ingolf-expedition. Marine animals -- Arctic regions; Scientific expeditions; Arctic regions. I quite agree with LuDWIG that the different varieties of Cucumaria abyssorum described by Theel are only developmental stages, and with this variation taken into consideration I have no doubt that the present specimens, previously mentioned as G.ingolf,, are but Atlantic specimens of Cabyssorum. Further this does not leave any doubt that Ohshima's species, C. sluiteri, must also be regarded as a synonym of C. abyssorum; then- are. in fact, mi differences between these two species. Textfig

Farther characters are the existence of a coclom, Iheamhulacral system, and the mesodermal spiny skeleton, which has given the name to the phylum. 3. The ambulacral system is locomotor and occurs nowhere else. It consists of a sieve-like madreporite (not always present), which passes water to the stone canal, and from this to the riirg canal and the five radial canals to fill the ampulkc and ambulacra. Lateral branches supply the tentacles and cause their extension.. Fig. -Cucumaria frondosa, sea cucumber (from Emerton). 4. Bloo

Selenka1 has studied and figured the larva of Cucumaria doliolmn which, although totally unlike an auricularian larva, can be well compared with a pupa. It is an elongated free swimming creature with four, sometimes five, transversely arranged ciliated rings, in addition to which, at the anterior end, there is a ciliated field. This ciliated field is one of the first of the larval structures to disappear as development progresses. In Selenka's figure of this larva, reproduce

XVI ECHINODEEMATA 535 In this form the first five lobes of the hydrocoele give rise to the radial canals, and the primary buccal tentacles arise from their bases. Now in Synapta the radial canals disappear in the adult, they are, in a word, vestigial functionless structures â , but in Cucumaria they persist and give rise to numerous paired tube feet. Therefore the mode of their development in Synapta is secondary, the method in Cucumaria typical and primary, and this typical and primary method is the same as that which oIdtains in other groups of Echinode

Farther characters are the existence of a coclom, Iheamhulacral system, and the mesodermal spiny skeleton, which has given the name to the phylum. 3. The ambulacral system is locomotor and occurs nowhere else. It consists of a sieve-like madreporite (not always present), which passes water to the stone canal, and from this to the riirg canal and the five radial canals to fill the ampulkc and ambulacra. Lateral branches supply the tentacles and cause their extension.. Fig. -Cucumaria frondosa, sea cucumber (from Emerton). 4. Bloo

The tentacles vary in number from eight to twenty and some- times more. These are supposed to be much-moflified tube feet, and are used to push food into the mouth. When the animal is disturbed, they can be greatly contracted and drawn completely back within the mouth. Sea cucumbers vary from two to fifteen inches in length, depending upon the species and the age of the incUvidual. One species of Cucumaria some
