Show 1890.] NEW ARANEIDEA. 621 confirms the interpretation above implied from the absence of the spines on the falces. This, however, cannot be taken as conclusive, inasmuch as in the genus Moggridgea, Cambr., there is a similar absence of spines on the falces, while in an allied genus (Dendricon, Cambr.) they are present; but the known Spiders of each of these two genera form their trapdoor nests in similar situations, i. e. in the interstices of the rough bark of trees. I a m also glad to be able to give a figure and description, in the present paper, of Dendricon rastratum, Cambr., a genus and species characterized and described some time since (P. Z. S. 1889, p. 250) from a few dried fragments of the Spider, which had been crushed to pieces in transit. The perfect specimen, now in the British Museum, bears out the generic distinction accorded to the fragments mentioned. Another very remarkable Theraphosid described below was received from India, from Dr. Walsh (of the General Hospital, Calcutta). It possesses only two spinners, and consequently needs not only a new genus, but a new subfamily for its reception. Along with the above-mentioned species is also described a fine Spider, nearly allied to the very remarkable Robsonia marina, Hector, which last lives in holes of the rocks in the sea below high-water mark, in N e w Zealand. I received no information as to the habits of the present Spider, but should imagine them to be like those of Dr. Hector's species. Among Mr. Abraham's S.-African Spiders were several adult specimens of Stegodyphus gregarius, Cambr., of which the large nest, numerously inhabited by Spiders of all ages, some time ago in the Society's Gardens \ came from the same quarter of the globe. Mr. Abraham, however, says that the nest of this Spider sometimes attains the enormous dimensions of twelve feet. Fam. THERAPHOSIDM. Subfam. DIPLOTHELID_E. (Spinners 2.) DIPLOTHELE, gen. nov. Characters of the Genus. Cephalothorax oval, rather truncated in front. Eyes very unequal in size, placed on a distinct protuberance, forming a square; the fore laterals and hind laterals occupy the four corners of the square, and are placed obliquely, cutting off the angles; the fore and hind centrals form a transverse quadrangle within the square, nearest the hinder part. Legs rather strong, moderately long, 4, 1, 2, 3, but not differing greatly in length; furnished with hairs and bristles only, a few of the latter beneath the tibiae and metatarsi of the third and fourth pairs being of a spinous character; the tarsi of the first two pairs terminate with a strong compact elaw-tuft, pointed in front; the terminal claws appeared to be two, curved, but not strong, and without, so far as could be seen, any denticulation. The claw-tuft on the two hinder pairs is less compact, not pointed, and more 1 Presented by Lord Walsingham. PROC. ZOOL. Soc-189U, No. XLII. 42 |
