After a nod of her head, Paulette's hand shot up and the auctioneer all but cheered as he looked about for another sucker, his voice sounding like an old Lucky Strike commercial.
3 b) can be protruded, apparently by the force of the blood-pressure, and by means of this A bladder - acting as a sucker - the insect obtains firm hold on any surface which (After H.
The viscid pulp soon hardens, affording a protection to the seed; in germination the sucker-root penetrates the bark, and a connexion is established with the vascular tissue of the first plant.
The body is composed of a small and limited number of segments (not more than fourteen), and there is a sucker at each end of the body.
14), and the presence of an anterior and posterior sucker, produce a looping mode of progression similar to that of a Geometrid larva.
Visceral sac and shell small in proportion to the rest of the body, which cannot be withdrawn into the shell; foot elongated, fin-shaped, with sucker, but without operculum.
Visceral sac very much reduced; without shell or mantle; anus posterior; foot provided with sucker in male only.
The sucker-bearing processes of Pneumonoderma are outgrowths of the proboscis.
There seems no doubt that the suctorial mouth-organs of the Diptera have arisen quite independently from those of the Lepidoptera, for in the former order the sucker is formed from the second maxillae, in the latter from the first.
For pumping a well a valved working-barrel with valved sucker is attached to the lower end of the tubing, a perforated " anchor " being placed below.
The sucker carries a series of three or four leather cups, which are pressed against the inner surface of the working barrel by the weight of the column of oil.
The sucker is connected by a string of sucker-rods with the walkingbeam.
There is usually fixed above the sucker a short iron valverod, with a device known as a rivet-catcher to prevent damage to the pump by the dropping of rivets from the pump-rods.
I, Aa) which is regarded as a sucker or as re lated to the uterine :; o o??

- Elongated cylindrical animals either with a single subterminal sucker at the proximal end, or with the corresponding end of the body converted into a mobile undulatory fold.
These complex organs have apparently arisen by the increase in depth and differentiation of an accessory sucker such as is borne on the phyllidia of the former group. Lastly, the scolex of the more familiar Taeniidae (Tetracotylea) carries a rostellum encircled with hooks and four cup-shaped suckers the margins of which do not project beyond the surface of the body.
In Florida, vigorous suckers are sometimes allowed to remain when the plant is cut, and produce a " sucker crop " inferior in character to the first or principal crop, but still serviceable.
The mouth lies usually in the centre of the anterior vzs and sub-terminal sucker or between two adoral suckers, but in Gasterostomum and its allies it is mid-ventral.
In the ectoparasitic Trematodes this post-oral sucker is a complex disk placed near the hinder end and provided With suckerlets, hooks and a musculature arising from a special skeleton.
Thus in the recently discovered arctic genus Prosorhynchus the muscular and glandular extremity is protrusible, but in the allied Gasterostomum this organ is represented by a sucker with fimbriated or tentacular margins.
The chief genital pore is placed anteriorly between the oral sucker and the ventral one, and is posterior only in Holostomidae, Gasterostomidae and a few Distomidae.
