Monhystera filiformis Biitschli, 1873. The second group of specimens has the amphids 1.4 - 2.7 head widths from the anterior end and is here regarded M.filiformis. Dimensions of 14 females: L = 0.29 - 0.50 mm; a = 27 - 37; b = 4. 1- 5.4; c = 3.5 -4.7; V = 1 4~ 2152 -59. Diameter of amphids 1.2-2.5 \i or 25 -40 % of corresponding body width. This form is slenderer than M. vulgaris. Length of tail equal to 9-14 anal body widths. The vulva-anus distance is 59 -91 % of tail length. The oesophagus in this form is relatively longer; the vulva on the average lies more anterior, contrary to the findings of Micoletzky (1914). A difference in development of lips between vulgaris and filiformis could not be observed. Samples 16, 24, 26, 30, 31, 33, 34, 57, 60, 61, 65 and 66. Published as part of P. A. A.
