MODIFICAI'TON OP THE EYK PKDUNCLES IN CYMONOMUS. 463 



The followinj^ remarks in reference to tlicse drawings and llie original 

 specimens are Jiindly furnished by Dr. W. T, Caiman, who is now engaged on 

 carcinological work in the Natural History Museum. 



" The specimen represented in Figs. 1 and 8 is a male, the carapace of whicii 

 measures about 3"1 mm. in length to the base of the rostral process. Fig. 10 

 is taken from a female specimen with carapace 4 mm. in length, and Fig. 11 

 from a male 2*4 mm. in length. 



" The originals of the other figures cannot now be identified. 



"In the specimen shown in Figs. 1 and S the eye-stalks are not quite so 

 near together at the base as in the figure, though they are somewhat nearer 

 than in the specimens from whicli Figs. 10 and 11 have been drawn. One of 

 these (Fig. 10) has at the tip of the eye-stalks a slight trace of the brownish 

 coloration which in normal specimens distinguishes the corneal area, but 

 this cannot be discerned in either of the other two specimens. 



" Fig. 12 shows a small scale (.r) apparently articulating with the end of 

 the proximal joint of the antennal peduncle. This appears to be exceptional 

 in occurrence, and is not present in the specimens examined by me. It seems 

 to be a development of the primitive third joint of tlie peduncle, usually fused 

 with the second and indicated only by a sutural line. — W. T. C."
