Dark brown, with six or seven obscure darker cross-bands, and 
numerous dark specks and niottlings, forming indistinct strii>es; tins 
all speckled, the caudal not darker than the other fins. Teeth very 
small, present on both sides of the Jaw; eyes very small, close together, 
the upper in advance, the lower just above angle of mouth. Ventral 
tin moderately developed, barely reaching anal, to which it is connected 
by a low membrane. Head 5; depth 3:|. 1). 95; A. SO; Lat. 1. 93. 
South Atlantic and Gulf coast to the West Indies; abundant in sandy 
bays.

Order V. — PEDICULATI. 
{The Pediculate Fishes.) 
Carpal bones notably elongate, forming a sort of arm, which sup- 
ports the broad pectorals. Gill-openings reduced to a large or small 
foramen, situated in or near the axils, more or less posttu-ior to the 
pectorals. iS'o scales. Ventral fins jugular, if present; first vertebrie 
united to the craninm by a suture; epiotics united behind sui)raocci- 
pital; elongate basal pectoral radii reduced in number; no interclavi- 
cles; posttemporal broad, flat, simple; superior pharyngeals two, sim- 
ilar, spatnlate, with anterior stem and transverse blade; basis of 
cranium simple. No air-duct to the swim-bladder. Anterior dorsal 
reduced to a few tentacle-like, mostly isolated, spines. This group is 
considered as a modified offshoot from Batmehoid or Blennioid forms. 
(Latin pedicnlatus^ provided with a little foot or peduncle, in allusion 
to the peculiar pectoral fins.)
