  • n. testacean rhizopods


Sorry, no etymologies found.


  • In the present state of science, it is chiefly by the aid of shells that we are enabled to arrive at these results, for of all classes the testacea are the most generally diffused in a fossil state, and may be called the medals principally employed by nature in recording the chronology of past events.

    II. Uniformity Of Change

  • The plants: Natives Chasmanthium latifolium Northern Sea Oats, a grass with dancing seedheads, and Aster laevis 'Bluebird,' a hit with butterflies, bees and birds, are paired with Carex testacea 'Prairie Fire' and Sedum sichotense, whose colors intensify as temperatures drop; bright chartreuse Lysimachia nummularia 'Aurea' adds to the show.

  • Hence we have good evidence that the above enumerated gigantic quadrupeds, more different from those of the present day than the oldest of the tertiary quadrupeds of Europe, lived whilst the sea was peopled with most of its present inhabitants; and we have confirmed that remarkable law so often insisted on by Mr. Lyell, namely, that the "longevity of the species in the mammalia is upon the whole inferior to that of the testacea."

  • The size of animals of cold constitution illustrates this particularly well, and hence snakes and lizards and scaly reptiles are of great size in warm localities, as also are testacea in the Red Sea: the warm humidity there is the cause equally of their augmented size and of their life.

    On longevity and shortness of life

  • But all those creatures which do not move, as the testacea and animals that live by clinging to something else, inasmuch as their nature resembles that of plants, have no sex any more than plants have, but as applied to them the word is only used in virtue of a similarity and analogy.

    On the Generation of Animals

  • We have now spoken of the generation of other animals, those that walk, fly, and swim; it remains to speak of insects and testacea according to the plan laid down.

    On the Generation of Animals

  • That all the testacea are formed spontaneously is clear from such facts as these.

    On the Generation of Animals

  • Because their nature answers to that of plants, therefore few or no kinds of testacea come into being on land, e.g. the snails and any others, few as they are, that resemble them; but in the sea and similar waters there are many of all kinds of forms.
