The species is immediately recognized by its elaters, whose numerous and lengthened spinules are unlike those of any cognate form, reminding one of the capillitium of Ophiotheca.
I have shown that the spinules develop in the mature males not as a modification of the scale, but as separate calcareous deposits the bases of which afterwards become united to the scale.
Dab: scales uniform all over the body, with spinules on the projecting edges, making the skin rough; lateral line with a semicircular curve above the pectoral fin.
The distal end of the radial spines is penicillate and bears a brush of bristle-shaped, radial, terminalspinules (compare Sagosphaera penicilla, p.
Some thicker forms of spines exhibit a remarkable structure, the surface being covered with small dimples and spinules between them (fig.
These spinules communicate with one another by tangential branches (at equal distances from the inner cortical shell), and form thereby an outer, delicate cortical network, with large polygonal meshes and very thin bars.
Network of the outer shell regular, with meshes of equal size and similar form; surface thorny or papillose, covered with small spinules or tubercles.
Spicula all geminate-triradiate, composed of a simple middle rod and of three diverging shanks on each end of it; the shanks are thorny with small spinules and shorter than the axial rod, very similar to the common Sphaerozoum punctatum.
Network of the outer shell irregular, with meshes of different size and form; surface thorny or papillose, covered with small spinules or tubercles.
The dorsal spinules are most pronounced and extensive on the male (Fig.
The illustration of the holotype suggests that it has equally prominent, but fewer, spinules (Gaige, 1926).
Cortex of minute spinules and granules or furfuraceous scales.
This is due to the colored spinules or setæ which clothe them.
Cortex a thin coat of minute spinules and granules, gray or brownish above, whitish below, finally falling away from the smooth, shining, pale or brownish surface of the inner peridium.
Cortex of long slender spines, mingled with smaller spinules and warts, gray brown or blackish in color; the longer spines first fall away, leaving a reticulate surface to the inner peridium.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "spinules" in a variety of sentences. We hope that you will now be able to make sentences using this word.
