ZOOLOGY OF THE VOYAGE OF H.M.S. SAMARANG. 
thorace subdilatato lateraliter supra insertiones secundi, tertii, et quarti pedum pariurn, sed inde ad frontis 
apicem omnino integro. 
Fronte ad extremitatem antcriorem declinata, a thorace liaud plane distincta, ultra medium emarginata, 
atque incisa untiee, efficieute duos lobos qui ad extremitates rotundati suut. 
Chelis sequalibus, subgracilibus, brevibus densis tenuibus setts coopertis; brachio subcylindrico ad 
oculos introrsum curvato, longis, fortibus, paululum eurvatis setis utrimque fimbriato ; carpo convexo et 
extrorsum inclinato ; manu lateraliter compressa, convexfl externe, concava interne, infra rotundata, supra 
subangulari ; digito breviore, lsevi, curvato, et minutim denticulato. 
Secundo et tertio paribus pedum thorace vix ter dimidioque longioribus ; imdto crassioribus, majoribus et 
longioribus quarto et quinto paribus ; tertio articulo cylindrico et antice paidlo latiore ; quarto articulo elongato, 
conicali, longis setis utrimque fimbriato ; quinto articulo tertio lougiore tertia parte, margine anteriore leniter 
curvato, posteriore dilatato, arcuato, longis, bene dispositis, ciliatis processibus retro directis utrimque 
fimbriato, supra leniter sulcato, infra profundis canalibus ; chelis dilatatis, admodum eurvatis, supra sulcatis, 
setis longis fortibusque utrimque fimbriatis ; apice curvato et acuto. 
Quarto et quinto pedum paribus thoracem fere ter longitudine superantibus; secundo et tertio paribus 
multo gracilioribus atque minoribus ; tertio et quarto articulo fere simili longitudine ; quinto articulo brevi, 
lato, depresso incurvato ; chelis dilatatis, acutis, et chelis reliquorum pedum crassioribus. 
IIab. Mare Mindorum. 
Front deeply incised, lobes of the front angular ; second and third pairs of legs very 
slender, nearly three times and a half the length of the carapace ; fourth and fifth pairs nearly 
three times as long as the carapace. 
Carapace about seven lines long and five wide, trigonal, broad behind, gradually 
becoming narrower towards the front, tomentose, and beset with numerous short, sharp, 
sting-shaped processes, particularly towards the hinder part ; middle and branchial regions 
separated by a rather superficial impression, posteriorly a transverse groove between the 
carapace and abdomen ; body hollowed out between the fifth pair of legs, carapace a little 
dilated laterally above the insertions of the second, third, and fourth pairs of legs, but per- 
fectly entire from this to the apex of the front. 
Front bent down towards the anterior extremity, not distinctly separated from the cara- 
pace, emarginate beyond the middle, and deeply notched anteriorly, forming two lobes which 
are rounded at the ends. 
Fore-legs equal in size, rather slender, covered with short, close-set, fine hairs ; third joint 
subcylindrical, curved inwards towards the eyes, fringed on each side with long, stiff, slightly- 
curved hairs ; fourth joint convex and bent outwards ; fifth joint somewhat laterally com- 
pressed, convex externally, concave internally, rounded below, rather angular above ; claws 
rather short, smooth, curved, and finely denticulated. 
Second and third pairs of legs nearly three times and a half longer than the carapace, 
much stouter, larger and longer than the fourth and fifth pairs ; third joint cylindrical, and a 
little wider anteriorly ; fourth joint elongated, conical, fringed on each side with long hairs ; 
fifth joint a third longer than the third joint, the anterior margin slightly curved, the posterior 
dilated, arched, fringed with long, regular, ciliated processes on each side, directed back-
