CHILOSCYLLIUM INDICUM. 65 



Described from a female, of about twenty-four inches, from Penang. In the 

 ovaries there is a number of small eggs nearly or quite ready to enter the ducts, 

 while in each of the latter there are two provided with shells, firm and blackish. 

 These shells resemble those of Raiidae more than those of Catulidae. The 

 angles are provided with short blunt processes without tendrils and at the distal 

 end the processes are brought closer together. One edge is longer than the 

 other and more curved; on the inner or shorter edge, near each end there is a 

 mat of long filaments, similar to those of raioids, to serve as anchors. The 

 structure is quite firm being heavily reenforced along the lateral edges. 



This species differs from C. punctatum in shape of head and snout, in the 

 longer spiracle, in the positions and in the lack of sharpness in the hinder angles 

 of the dorsals, and in the lengths of anal and subcaudal respectively. From C. 

 griseum it is distinguished by smaller dorsals, with positions and non production 

 of angles, by the distance of the second dorsal forward from the anal, etc. 



India to South Africa and Japan.

Body slender, cavity little more than one third of the total length; head 

 little more than one sixth, rather narrow, depressed on the crown; snout medium, 

 blunt. Nostrils with nasoral grooves; anterior valves and cirri reaching the 

 mouth, separated by the moderate preoral attachments; posterior valves form- 

 ing a fold at the outer side of each nostril and continuing in another on the 

 outer side of the nasoral groove, to end in a short free fringed extremity at the 

 angle of the mouth, subcontinuous with the upper labial fold. Mouth small, 

 with short labial folds on both jaws, and with a narrow transgeneial fold behind 

 the symphysis, in front of the lower labial folds. Eye small, elongate, lower lid 

 without a fold. Spiracle small, its front edge below the hind edge of the orbit. 

 Gill openings narrow, hindmost widest, third to fifth above the pectoral, fourth 

 and fifth close together.
