BEDDARD ON THE STRUCTURE [Mar. 5, The penial setce are illustrated by the accompanying drawing (text-fig. 57); the distal end of each seta is but faintly ornamented with a few transverse ridges. Text-fig. 57. Typhoeus incommodus, penial seta, greatly magnified. The spermathecce are large globular sacs. The diverticula form a complete frill of small sacs round the duct of the spermatheca. Typhoeus masoni Bourne. Typhoeus masoni A. G. Bourne, J. A. S. B. lviii. p. 112. Prof. Bourne examined and reported upon a single individual only of this species from Dehra Dun. 1 have acquired a second specimen, also fully mature, from the same locality and beg to offer a few notes thereon. M y specimen measures 146 m m . in length. Beyond observing that the anterior segments are bi- to quadr-aunulate, the description of the species gives no details of the annnlation of these segments. As this matter appears to be of specific value, I give a detailed account of the annulation in elucidation of the accompanying woodcut (text-fig. 58). The first segment is simple ; the second is fairly annulate, the third and fourth very decidedly so. In both of them the setae are implanted upon the first of the two annuli. The fifth ring is primarily bi-annulate, but each annulus is again subdivided. The next segment is divided into three marked annuli, of which the middle one bears |
