In many blood-sucking flies, for example, the galea is absent, while the lacinia becomes a strong knife-like piercer and the palp is well developed.
In butterflies and moths the lacinia is absent while the galea becomes a flexible process, grooved on its inner face, so as to make with its fellow a hollow sucking-trunk, and the palp is usually very small.
Mandibles present in pupa, vestigial in imago; maxillae suctorial without specialization; first maxillae with lacinia, galea and palp.
The galea sometimes forms a palpus-like appendage.
The maxillæ; end in a tridentate lacinia as usual, though the palpi and galea I have not yet studied.
The central bivalve lattice-shell, from which the galeaand the tubes arise, exhibits in {1741}the Coelographida essentially the same form and structure as in the preceding Coelodendrida.
The two valves { Galeawithout rhinocanna of the bivalved { or nasal tube, without shell very thin { frenula, 14.
From this apex there arises on each valve an irregular conical or three-sided pyramidal cupola, the galea (Pl.
A conical cupola or a pyramidal galea arises from the apical pole of both valves, therefore at the opposite poles of the sagittal axis.
The two pectoral or anterior paired tubes always arise from the galea itself whilst the posterior odd or caudal tube usually arises behind the galea from the valve (Pl.
Galea hemispherical, separated from the cephalis by a sharp horizontal stricture; pores smaller.
In the majority of species observed, this odd sagittal tube is forked even at its origin, so that two divergent tubes (an anterior and a posterior) arise from the apex of the galea (Pl.
Pores in the galea and thorax very small and numerous, circular, in the cephalis much larger, irregular, roundish.
Spyroidea# without galea and thorax; the shell consisting of the bilocular cephalis only and its apophyses.
Hollow tubes, arising from the galea of both valves, dichotomously branched; the branches anastomose and form an outer bivalved lattice-mantle.
Galea hemispherical, with numerous small irregular, roundish pores, about half as long as the cephalis, with a slender conical horn of twice the length.
Coelographida# with an odd sagittal frenulum on each galea and an outer lattice-mantle, armed with ten styles (one odd and four paired styles on each valve).
The two nasal tubes or rhinocannae (a dorsal and a ventral) lie in the sagittal plane of the body and run from the base of eachgalea along the anterior convexity of the valve to its oral margin.
Coelographida# with an odd frenulum on eachgalea and an outer lattice-mantle, armed with fourteen styles (one odd and six paired styles on each valve).
The central capsule with its nucleus; on the left side one valve of the closely enveloping shell (seen in vertical section), and its galea with the origin of the four tubes.
One valve of the shell (h) with its large galea and the origin of the three styles.
One valve of the shell, with its galea and the four tubes arising from it.
One valve of the shell, with its galea and the four hollow forked tubes arising from it.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "galea" in a variety of sentences. We hope that you will now be able to make sentences using this word.
