lAPTdRIAL CLAW OF FEMALE LYSIOSQUILLA 

 HLMINIENSIS. 



tbe posterior lateral lobes of the carapace are bordered by a narrow- 

 band of deep black, separated from the rest of tlie carapace by a similar 

 band of bright lemon yellow, form- 

 ing conspicnous eye-spots. There 

 are also two pairs of yellow and 

 black stripes on the last thoracic 

 and on the fifth abdominal segments 

 bordering the posterior margin for 

 some distance inward from the 

 angle, and the tclson has a pair 

 of black eye-spots edged in front 

 with yellow, one on each side of the 

 median line, jnst in front of the 

 dorsal spines. All except the black 

 markings wash ont in alcohol.

The collection contains a female and a mntihated mak^ from the 

 stomach of a flounder. They were dredged by the IT. S. Fish Commis- 

 sion steamer Fish Hawl; at stations 1247 and 1251, southwest of Gay 

 Head, Martha's Vineyard, at a depth of 27 and 17 fathoms, bottom sand 

 (No. 12787, U.S.N.M.). Although these specimens were identified by 

 Prof. Smith himself, as shown by the label, they differ somewhat froni 

 his description. The eyes in both specimens are not large and are only 

 a little more than half as broad as the rostrum. The posterior part of 

 the body of the male is destroyed, but in the female the posterior mar- 

 gins of the fourth, fifth, and six abdominal segments and the lateral 

 margins of the telson in front of the lateral spines are smooth, entirely 

 devoid of the slender spines or spiuules described by Smith. It may 

 be that the possession of these spiuules is a sexual character of the 

 male. The telson of the female has six well-developed marginal spines, 

 the submedian pair being very slender and mobile. Tliere are seven to 

 nine very small submedian denticles on each side, four intermediate 

 ones, two of them being very large, flattened, and rounded in outline? 

 and two others alternating with them, being very small and acute, and 

 there is one small lateral denticle on each side. The rostrum is tipped 

 with a small spine.
