Species Monstrilla conjunctiva - Plate 1 of morphological figuresissued from : R.B.S. Sewell in The John Murray Expedition, 1933-34, Scientific Reports, IX (2), 1949. [p.137, Fig.38] .
Male (from Nankauri Harbour, Nicobar Is.): A, habitus (lateral left side); E, P1.
Nota: Proportional lengths of the various segments of the body as 513:123:88:70:40:35:26:22:13:70 = 1000. Mouth-opening divides the anterior region (pre-oral) and posterior region (post-oral) as 1 to 1.5. Abdomen 4-segmented. Genital segment bears ventrally a sac-like protuberance that terminates on each side in a conical projection; on the postero-lateral border of this sac, abot half-way along its length is a spine-like process that is thick at the base and tapers to the free end and is serrated along its outer margin. Caudal rami of nearly equal in length to the last three abdominal segments, each with 4 setae. A1 5-segmented (2nd and 3rd partially fused; proportional lengths as 15:16:21:25:23 = 100; the 1st segment devoided of any setae. P5 represented by a long seta that arise from the posterior border of the segment and reaches to the end of the caudal rami.

Female: B, habitus (dorsal); C, 5th thoracic segment and abdomen (ventral); D, P2.
Nota: Proportional lengths of the various segments of the body (cephalon to caudal rami) as 653:82:65:49:37:43:17:11:43 = 1000. Abdomen 3-segmented. Caudal rami about 4 times the length of the anal segment, each ramus bears 5 setae. P5 consists of 2 flat plates, each with 2 setae on iits distal margin
