NOTES ON OPHIOGLYPHA. 

 Ophioglypha falcifera Ltm. 



Plate IV. Figs. 37-39. 



In the original description (Bull. Mas. Comp. Zool., I., No. 10, p. 320) I 

 said : " We may look for an adult of this curious species about the size ol 

 O. Sarsii, or rather smaller, and having a large number of small plates on the 

 disk." 



A considerable number of specimens were brought in by this expedition, of 

 which the largest had a disk of 13 mm., and the arm 52 mm. long. The disk 

 was covered by coarse, well-defined scales, the interbrachial margin being al- 

 most wholly occupied by a single plate. The hook-like form of the middle 

 arm-spine could be traced to within half a dozen joints of the disk.
