Jasmineira bilobata New Species 



P^ijrui'f ITiii-v 



Hdidt !!])(. — USNM 4.3134; one paratyjie, 

 USNM 43135. 



Drscription. — Holotype incomplete, very slen- 

 der, measuring 9 mm by 0.5 mm for 19 seg- 

 ments. Branchial lobes (Figure 17t) long and 

 slanting, each with eight radioles united only 

 at base. Each radiole with paired pinnules in- 

 creasing in length distally, tip slender, hardly 

 distinguishable from terminal jiinnules. Ventral- 

 most radiole much shorter than others with 

 only two or three stumpy pinnules basally. 

 Palps short and grooved. Li])s with bagg\' ven- 

 tral pouches (Figure 17s) partly covered by 

 notched ventral projections of collar. Collar 

 with two closely apposed dorsal lobes (Figure 

 17v), low lateral parts and ventral lobes pro- 

 duced forwards as notched lappets; dorsolatei-al 

 notches between dorsal lobes and low lateral 

 parts of collar. Thoi'ax with eight setigers; first 

 short and united to collar, remainder slightly 

 broader than long. Setiger 1 with winged cai)il- 

 laries only; setigers 2-8 with one or two winged 

 capillaries (Figure 17p) and four paleae (Figure 

 17o) having oval blades and short, finely pointed 

 tips. Thoracic neurosetae as a row of five long- 

 shafted hooks (Figure 17m, n) with a swelling 

 at origin of shaft and a rostrum capped with a 

 close-set series of denticles and a faint indica- 

 tion of a hood. 



Abdomen broken after segment 9. Abdominal 

 neurosetae include three winged capillaries 

 (Figure 17q) and shorter forms with hastate 

 blades embedded in the flesh. Abdominal 

 notosetae as avicular uncini (Figure 17u, v) 

 with four or five close-set arcs of denticles 

 above rostrum and short, laterally compressed 

 bases. 



R( nuii-kx. — The .shajie of the collar immedi- 

 ately distinguishes J. bilobuta from the well- 

 known European species J. cIcc/cDh^ Saint- 

 Joseph, .7. cu II do la Langerhans, and J. eundcki 

 (Grube). Possibly the most clo.^ely related spe- 

 cies is J. filifhrnii^ Hartman (1965a) from deep 

 water off Brazil. It too, has a collar with elon- 

 gated ventral lobes and thoracic hooks with a 

 swelling at the origin of the shaft. Hartman's 

 description is vei-y brief but her figure does not 

 show dorsal lobes to the collar or notches in 

 the elongated ventral lobes. Moreover there are 

 only four pairs of radioles and there is no men- 

 tion of paleae among the thoracic notosetae. 



Ric(n-ds. — Two specimens off Beaufort in 

 123 m (*). 



? Oriop.sis sp. 



D>sc)-iptii>ii. — Length 3.5 mm including bran- 

 chiae; 11 thoracic and 19 abdominal segments. 

 Three pairs of flanged radioles. Collar low dor- 

 sally, widening laterally and forming two united 

 triangular lobes ventrally; margin of collar 

 smooth. Thoracic notopodia with three winged 

 capillaries and two paleae bearing oval blades 

 and fine tapering tips. Thoracic neurosetae as a 

 row of four or five long-shafted hooks each with 

 one large tooth and a close-set cap of small 

 denticles above i-ostrum. Abdominal uncini 

 almost square and arranged in rows of six or 

 seven per notopodium. Individual uncini with a 

 recurved basal prow and main fang surmounted 

 by three or four rows of smallei- teeth with four 

 teeth per row. 



Remarks. — The presence of paleae among 

 the thoracic notosetae and the numerous ab- 

 dominal segments are unusual in the genus 

 Or/();).s(.s-. Oridia crcnlcollix Annenkova, shares 

 these characters and is doubtfully referred to 

 Oriopsi.'< by Ban.se (1957). It differs from the 

 Beaufort material in having a scalloped edge 

 to the collar.
