Fig. 133. Loxorhynchus crispatus, 3, X 4%; a, dorsal; b, lateral view of 
rostral region (after Stimpson). 
Characters——Carapace rather narrowly triangular, not nearly so wide or 
inflated as in L. grandis; covered with a short, thick felt-lke coat of hair; with 
nine to twelve prominent tubercles; hepatic region with one large spine. Rostrum 
but slightly depressed as compared with L. grandis and with more divergent horns. 
Dimensions.—Type, male: length of carapace 87.6 mm., greatest width 57.4 mm. 
The carapace of a single specimen brought in from Point Reyes was 57 mm. in 
length. 
Color.—Beneath the pubescence bluish white, the rostrum, spines, and feet 
being of a bright carmine hue (Stimpson). Im alcohol the color ranges from 
reddish brown to tan; the carapace after removal of the hair often shows red 
markings, especially about the tubercles (Weymouth). 
Type Locality —San Miguel Island, California. 
Distribution.—From Point Reyes and the Farallon Islands to San Diego, Cali- 
fornia; 4 to 53 fathoms. 
Remarks.—These erabs are generally found so thickly covered with foreign 
growth, such as hydroids, seaweeds, bryozoans and sponges, that in their natural 
environment they are scarcely recognizable as crabs at all (Holmes). 
Genus Scyra Dana 
Carapace subpyriform, tuberculated, but not spinose. Rostrum composed of 
two short, flattened horns. Basal antennal joint deeply concave, with outer margin 
flattened and produced but not spiny; next two joints flattened, with thin, broad 
lateral expansions. Preocular spine present, acute; postocular deeply cupped on 
anterior face and without hairs; orbits small, deep, with a fissure above and 
below, the lower and sometimes the upper being open.
