The Carter, Shepherd Spider, or long-legg’d Spider, has, for two particularities, very few similar creatures that I have met with, the first, which is discoverable onely by the Microscope, and is in the first and second Figures of the 31. Scheme, plainly describ’d, is the curious contrivance of his eyes, of which (differing from most other Spiders) he has onely two, and those plac’d upon the top of a small pillar or hillock, rising out of the middle of the top of its back, or rather the crown of its head, for they were fix’d on the very top of this pillar (which is about the heighth of one of the transverse Diameters of the eye, and look’d on in another posture, appear’d much of the shape, BCD.) The two eyes, BB, were placed back to back, with the transparent parts, or the pupils, looking towards either side, but somewhat more forward then backwards. C was the column or neck on which they stood, and D the crown of the head out of which that neck sprung.
These eyes, to appearance, seem’d to be of the very same structure with that of larger binocular creatures, seeming to have a very smooth and very protuberant Cornea, and in the midst of it to have a very black pupil, incompassed about with a kind of grey Iris, as appears by the Figure; whether it were able to move these eyes to and fro, I have not observ’d, but ’tis not very likely he should, the pillar or neck C, seeming to be cover’d and stiffen’d with a crusty shell; but Nature, in probability, has supply’d that defect, by making the Cornea so very protuberant, and setting it so cleer above the shadowing or obstructing of its prospect by the body, that ’tis likely each eye may perceive, though not see distinctly, almost a Hemisphere, whence having so small and round a body plac’d upon such long leggs, it is quickly able so to wind, and turn it, as to see any thing distinct. This creature, as do all other Spiders I have yet examin’d, does very much differ from most other Insects in the Figure of its eyes; for I cannot, with my best Microscope, discover its eyes to be any ways knobb’d or pearl’d like those of other Insects.
The second Peculiarity which is obvious to the eye, is also very remarkable, and that is the prodigious length of its leggs, in proportion to its small round body, each legg of this I drew, being above sixteen times the length of its whole body, and there are some which have them yet longer, and others that seem of the same kind, that have them a great deal shorter; the eight leggs are each of them jointed, just like those of a Crab, but every of the parts are spun out prodigiously longer in proportion; each of these leggs are terminated in a small case or shell, shap’d almost like that of a Musle-shell, as is evident in the third Figure of the same Scheme (that represents the appearance ot the under part or belly of the creature) by the shape of the protuberant conical body, IIII, &c. These are as ’twere
