NOTES ON OPHIOGLYPHA. 

 Ophioglypha falcifera Lym. 



Plate IV. Figs. 37-39. 



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

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

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

 disk." 



A considerable niimber 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.

Ophioglypha variabilis Ltm. 



Specimens from about thirty stations showed a good deal of variation. Some 

 were like Fig 70, PI. III., Bull. M. C. Z. V., No. 7, while others had two or 

 three vertical rows of scales in the lower interbrachial spaces. The scales on 

 the back of the disk also varied in size and number. Likewise the second or 

 under arm-comb had sometimes numerous and sometimes very few papillae.
