250 
The colour of this fpecies is an olive brown, marked 
with bluifti lines, and, toward the tail, with brown fpots. 
The peftoral fins have each twelve rays, the anal two* 
and the dorfal, which was two inches long, has forty* 
Between the vent and the tail, is a groove fix inches and 
an half long, covered by two valves. This is the recep' 
tacle for the young; and as thefe animals are viviparous» 
on treading upon this part, hundreds of living young* 
arc feen to creep out around the parent fifh. 
There are three fpecies of the pipe fiih found in the 
Britijb feas ; tlie longer, above defcribed, the lhoiter* 
and the fmall pipe fifh, or ophidion of Linnxus. Tl> e 
laft feldom exceeds five inches in length, is very flcndei'* 
and tapers off to a point at the tail, having no fin there* 
The pe&oral fins are alfo wanting, and the body is co- 
vered with a fmooth fkin, inftead of the cruft peculiar t0 
this genus. This fpecies is not viviparous, and coiif e ' 
quently the groove under the belly, does not contain h v ' 
ing young, but eggs, which are large, and. not very n 0 ' 
merous.
