Nymphum Hirsutus. 
N. pedibus longissimis hirsutis, mandibularum digitis inequalibus per totam longitudinem conni- 
ventibus. 
Nymphum Hirtum, Fabr. Syst. Ent. v. 4. p, 417? 
A second species of Nymphum was found associated with the preceding, 
which it resembles in general conformation and size, but differs in the follow- 
ing particulars: the legs, mandibles, and palpi, are thickly set with hair; 
the curved fingers of the mandibles are not of equal length, and meet along 
their whole inner edge ; the thighs are cylindrical, and not compressed in 
any individual; the first joint of the tarsus is extremely short; and the 
rostrum does not narrow towards its termination, as does that of the N. 
Grossipes. 
Phoxichilus Proboscideus. 
Pb. proboscide corpore duplo longiore, mandibulis nullis, palpis inungulatis. 
One perfect, and several imperfect, individuals of an undescribed species of 
the class Pycnogonides, were found at ebb tide on the shores of the North 
Georgian Islands. In the arrangement of Lamarck, this species is compre- 
hended in the genus Phoxichilus, and establishes a sub-division of the genus 
which had been anticipated, characterized by “ palpi without mandibles.” 
Body ovate, of four segments with lateral tubercles for the articulation of 
the legs, convex on the back, one segment only, the anterior, being marked 
by a transverse line: proboscis more than twice the length of the body, 
being one inch eight-tenths, and the body three-quarters of an inch long. This 
huge proboscis is nearly cylindrical, the extremity obtuse, with a triangular 
perforation, which influences in some measure the external shape. The dia- 
meter of the proboscis at the insertion and for a quarter of its length two- 
tenths of an inch, widening suddenly to thirty-five hundreths, and gradually to 
above four-tenths at the end. The anterior segment furnishes the palpi, and in 
the female the spurious legs ; and has on the back a conical tubercle, on which 
two eyes only were distinguishable in the most perfect specimen, when it was
