In the Atlantic this species has been recorded from Antigua, W. Indies (Stebbing)' 
and the larva, Lysterichthus duvaucellii, Guérin, has been recorded by Hansen (1895) 
from the vicinity of the Cape of Good Hope (32° 30’ S., 15° 0’ E.). 
var. sulcirostris, nov. 
Plate VIII, figs. 92, 93. 
This variety differs from typical specimens in the following points :— 
1. The rostrum is triangular, widest at the base, and is produced to a much sharper 
point than in typical L. maculata. In the anterior. two-thirds there is on each 
side a sharply-defined and deep groove running parallel to the lateral margin 
(fig. 92). : 
2. The dactylus of the single male specimen resembles that of typical male ma- 
culata, but has only eight teeth including the terminal one (fig. 93). 
3. The sixth abdominal somite is grooved as in the typical form, but much less 
distinctly, and the irregular wrinkling on either side is absent. 
The colour pattern is closely similar to that of L. maculata, but the dark trans- 
verse bands are much narrower than in typical examples of the species. 
L. sulcivostris is perhaps specifically distinct from L. maculata, but its resemblance 
to the latter form is so great that I hesitate to adopt such a course on the evidence of 
a single specimen.

De Vis’ description of the only known specimen runs as follows :— 
‘* Carapace smooth, in the form of a truncate isosceles triangle, rounded at the 
posterior lateral angles. Rostrum elongate, cordiform, acuminate, with a median ridge 
on its produced limb. Exposed segments with irregular longitudinal wrinkles on the 
dorsum, which is slightly depressed, the wrinkling and depression becoming more pro- 
nounced posteriorly. Anirregular semi-lunar depression on each segment near the lateral 
line. Penultimate segment, narrow, deeply sculptured in a grotesque fashion. ‘Telson 
smooth, with a bold sagittate median ridge and four teeth on the lateral margin, of which 
the anterior two are strong. ‘Ten long sharp teeth on the dactyli of the raptorial limbs 
including the terminal one, which near the tip is anteriorly dilated and presents a sharp 
edge. All the teeth finely serrated on the posterior edge. Four long sharp teeth on 
the propus, the posterior one moderately recurved. 
' According to Stebbing’s account the specimen from this locality differs from any Indo-pacific ex- 
ample that I have seen in having the fifth pleon segment denticulate along the hind margin, the sixth 
denticulate in an arched proximal band and round the distal margin, and the telson with three spines on 
each side and the truncate portion cut into five square teeth on one side and six on the other side of a small 
median emargination.
