PACIFIC SCIENCE, Vol. XII, April, 1958 
the first Pacific record for this genus, but, inso- 
far as I have been able to determine, because 
there are only five other published cases of 
cyamids infesting the small, toothed cetaceans 
commonly referred to as dolphins and porpoises. 
In four of these cases the cyamid involved was 
Isocyamus delphinii (Guerin-Meneville) and in 
three instances the hosts were unidentified dol- 
phins (Guerin-Meneville, Iconographie du regne 
animal , II, pi. 28, fig. 5, 1836; Barnard, Dis- 
covery Rpts. 5:314, 1932). In one case the host 
was Delphinus delphis (L.) (Liitken, K. Danske 
Vidensk. Selsk. 10: 433, 1873). The other example 
is that of Cyamus chelipes Costa (Mas. Zool . Univ . 
Napoli , Ann. 3: 82, pi. 4, fig. 2, 1863), which 
was taken from an unnamed dolphin. Although 
Costa’s figures are schematic, it is obvious from 
them that his species belongs in the genus 
Syncyamus . It is impossible to tell from Costa’s 
account whether chelipes is conspecific with the 
Gulf of Mexico and Panama Bay specimens. 
It is evident that additional collections of 
cyamids from porpoises and dolphins are needed 
for basic taxonomic studies, and those who have 
the opportunity to make such collections can 
greatly aid in filling in the gaps in our knowledge 
of these interesting amphipods. — Thomas E.

B. insignis Gray forma citrina C. N. Forbes & 
Lydgate, B. P. Bishop Mus., Occas. Papers 6 
(4): 11(203), 1917. This plant in the Lobeliaceae, 
known only from the Haupu Range, Kauai, 
differs constantly from the only other species, 
B. insignis , by having the corollas lemon yellow, 
the calyx lobes 0.8-1 mm. long, and the seeds 
conspicuously papillose. It is judged to be 
worthy of specific rank.— -Harold St. John , Uni-
