Show 682 REV. O. P. CAMBRIDGE ON A N E W SPIDER. [June 7, round the neck a little behind the head, thirty-three round the middle of the body. Ventrals 354, nearly uniform in size, each about double the width of the adjoining scales, and bituberculate, except towards the head and close to the anus. Six praeanal shields l. Terminal scale of tail considerably larger than the others. About thirty-five diamond-shaped black spots on the back, each broader than long, becoming gradually fainter behind ; head, sides, and belly yellow ; a black spot at the end of the tail. The only specimen is a male, and measures 66 inches, of which the head is 1 and the tail from anus 4f. Circumference of neck 2*1 inches ; of thickest part of body about 4. The nearest species to this, so far as I can see, is H. robusta 2, which is a stouter, less elongate form, with smooth ventrals, differently shaped and less elongate scales, those in the middle of the body being as high as they are broad, and having the tubercle sub-centrally instead of posteriorly situated on each scale throughout the anterior part of the body. The anterior temporal is large; but there is no large posterior shield on the temple, and there are three shields along the outer margin of each occipital, instead of two. The vertical is pointed in front. The black rings in H. robusta extend completely round the body. I have not been able to find, the place named as the locality (Gangestun); it is doubtless on the shores of the Persian Gulf, and probably near Bushire. VlPERA OBTUSA. Tehran hills. ECHIS CARINATA.

The chief interest attaching to this Spider lies in the fact of its having been received alive from Bahia, and having lived in the Gardens ot the Society from the beginning of March to October 1880 It appears to have died soon after casting its skin, when it probably attained maturity; but upon this latter point it is impossible to speak with certainty, inasmuch as the cutting-open of the under-surface of the abdomen, in order to preserve the Spider, had destroyed 2 IS °nll enteJ the.anal margin ; but I think six is the proper number p. 364 g" y8'SerP' U' P- 5 ° 5 ' P1" XTiii* fiSs* 8-10 - fltoflt, EeptBnt ind. |
