262 CEYLON PEARL OYSTER REPORT. 



series of projecting overlapping scales ; mediae! of the dorsal fascicle the simple setae 

 are shorter and hyaline. The ventral ramus carries a superior bundle of simple 

 whorled seta?, the verticillate tract short. All the remaining ventral setae are of the 

 compound falcigerous type, bearing very long, many-jointed, tapering, bidentate 

 appendices, the number of joints being as many as ten. The compound setae of the 

 middle group are characterised by the possession of squamose (fringed) shafts, while 

 the more slender setae of the inferior group have plain shafts. A parapodium from the 

 posterior region (near the 60th segment) shows the dorsal ramus projecting clearly 

 beyond the ventral, and in the ventral fascicle, in addition to the compound setae with 

 the long, jointed, flexible appendices, there are two stout setae with short unjointed 

 appendices provided with a gaping beak (Plate III., fig. 55). Between 50 and 

 60 segments are present in the imperfect sjsecimen described above, which is 

 35 millims. long with width of 3 millims. without the setae, 4 millims. over the setae. 



Family: PHYLLODOGID^. 



Anaitis zeylanica, n. sp. Plate III., figs. 57 to 60. 



Locality : South of Manaar Island, 8 to 9 fathoms. One specimen, proboscis 

 retracted. 



The dorsal phyllodes are broadly ovate (cordate-lanceolate) and pedunculate, as they 

 are in a dozen other species. Head rounded ; eyes large ; tentacular cirri normal, 

 elongate. Proboscis (dissected) consists of two well-separated portions, a thin-walled 

 proximal or adoral portion densely crowded with papillae not serially disposed ; a 

 thick-walled distal portion with six prominent rows of large subtriangular papillae, six 

 or seven in a row. 



Setae, ten in a parapodium, the shaft terminating in a triangular apex fringed at 

 the sides and articulating on one side with a long flagelliform strongly serrulate 

 appendix (Plate III., fig. 57). Anal cirri (one preserved) of moderate length, 

 acuminate with stout basal portion. Body slender, length 38 millims. ; total width 

 under 2 millims. 



The setae appear heterogomph in side view, homogomph in frontal view (Plate III., 

 fig. 58). I am afraid they offer no reliable diagnostic character, unless it is their size. 

 In this, however, as in other points they resemble the setae of Phyllodoce sancti- 

 josephi. The shape of the head and of the phyllodes is shown on Plate III., figs. 59 

 and 60. 



Carobia castanea, Marenzeller. 



Marenzeller, 'Siidjapan. Ann.,' i., 1879, p. 127 (p. 19 of reprint). 



This species is distinguished from other Oriental Phyllodocidae by its deep red 

 colour. 



The red dorsal phyllodes are cordate and the setae are distinguished from all others
