Elementary text-book of zoology, general Elementary text-book of zoology, general part and special part: protozoa to insecta elementarytextbo00clau Year: 1892 :;—:. 195 In their whole developmental cycle they agree very closely with uni- cellular algie and fungi; still the analogy to the developmental processes of many Infusoria, Amphileptus, is not to be passed over. iSjntmella vuhjaris {termo Ehrbg.) of Cienkowski shows a somewhat ditierent development and cyst formation; it receives solid food (by aid of the food vacuoles) and is lixed by a libre, as also Chromulina nebulosa Cnk., and Ochracea Ehrbg. A second group nearly allied to the Algse (Frotococcacea) is that of the Volvocin'uke. These organisms consist of colonies of cells united by a common gelatinous substance, and the following characteristics indicate their close relationship to the Algai:—(1) in the inactive stage tliQy possess a cellulose membrane; (2) they exhale oxygen; (3) they possess an abundance of chlorophyll and of vegetable red or brown coloured oils.
