The spiral striae that cross its whorls are grouped in pairs; their interstices are raised, and more or less finely crenulated; as they pass out on the expanded and wing-like varices they diverge, and the lobe-like projections that scallop the margins of the wings are separated from each other by each pair of diverging striae.
I have not the slightest doubt that there are twice that number as distinct from each other as these three are. First, then, we have the "striped" hyena already mentioned. He is usually of an ashy grey colour with a slight yellowish tinge, and a set of irregular striae, or stripes of black or dark brown.
Several fish, resembling an eel in shape, were caught today; they were of different sizes, and some of them gave a slight shock on being touched. They were marked across the back with alternate striae of silver, and various shades of brown and black, though there were scarce two marked exactly alike.
Occasionally the younger man made a remark in a low tone, and the elder wrote something on a card. "The 'seeing' is poor to-night," said Evarts, the younger man. "The upper air is full of striae and, though it seems like a clear night, everything looks dim a volcanic haze probably. Perhaps the Aleutian Islands are in eruption again." "Very likely," answered Thornton, the elder astronomer.
August 21. There were a great many crabs of different kinds and sizes caught today; two kinds of shrimps, one marked across with alternate striae of silver and dark brown; it had no antennae, and had apparently been hurt, as I could only see some very short legs; the rest appeared to be of the same kind as others recently caught, except being of a lighter colour.
We also often observe striae and furrows, as in Norway, Sweden, and Scotland, which deviate from the direction which they ought to follow if they had been connected with the present line of drainage, and they, therefore, imply the prevalence of a very distinct condition of things at the time when the cold was most intense.
Surface longitudinally striated, the cellular structure being hidden in calcareous spar; the striae formed by the coalescing lamellae, which, at the extremities, seem to be occasionally denticulated, owing to the matrix interrupting their passage to the edge. This resembles what takes place in some Astraeidae.
The striae seem as if the rock had been partially molten: at times the strike is north and south, at others east and west; when we come to what may have been its surface, it is as if the striae had been stirred with a rod while soft.
Now some or all the marks above enumerated, the moraines, erratics, polished surfaces, domes, striae, and perched rocks are observed in the Alps at great heights above the present glaciers and far below their actual extremities; also in the great valley of Switzerland, 50 miles broad; and almost everywhere on the Jura, a chain which lies to the north of this valley.
The colour of the legs, dark prussian blue; body of a silver colour in front, with a prussian blue colour behind; under part of the body, near the tail, three consecutive striae of a silver colour, separated from one another by a line of prussian blue. I have never seen this animal before. August 9.
